BC= 5cm
by calculation deduce whether triangle ABC is right-angled triangle
Answers
9514 1404 393
Answer:
not a right triangle
Step-by-step explanation:
The perimeter is 22, so we have ...
AB +BC +CA = 22
8 + 5 + CA = 22
CA = 22 -13 = 9
If this is a right triangle, the sum of the squares of the short sides will be equal to the square of the long side.
AB² +BC² = 8² +5² = 64 +25 = 89
This is not the same as ...
CA² = 9² = 81
The triangle is not a right triangle.

If you're familiar with a few Pythagorean triples, you know that a couple involving a side length 5 are (3, 4, 5) and (5, 12, 13). That is, (5, 8, 9) is NOT a Pythagorean triple, so you know immediately that those side lengths do not form a right triangle. (No calculation is necessary.)

What is an absolute value?Absolute value of a number is the distance value from zero without considering sign of a number. It is also represented as |x|, where x is any number.
Absolute value of a positive number is that same positive value. Distance of a positive number from zero is that positive number.

Answers
Answer:
x-intercept = 4
y-intercept = -1
As ordered pairs they would be ( 4, 0) and ( 0, -1)
Step-by-step explanation:
The line goes through 4 on the x line and goes through -1 on the y line.
As an ordered pair you just put the numbers in their x and y spots being ( x, y )
With 4 being on the X and -1 being on the Y it would make them ( 4, 0) and

The similar triangles are Δ ABC ~ Δ EDF ~ Δ GHI, both the triangles are similar to Δ ABC.
What are similar triangles?Triangles are similar when their corresponding sides are equal ratios and their corresponding angles are congruent.
Given are triangles, Δ ABC, Δ EDF and Δ GHI,
Since, in Δ ABC and Δ EDF, two angles are shown congruent therefore, both are similar.
Also,
In Δ GHI,
∠ G + ∠ I = 129°
∠ H = 180° - 129°
∠ H = 43°
Since, we get, two angles congruent in both triangles Δ EDF and Δ GHI
Therefore, both the triangles Δ EDF and Δ GHI are similar,
Now,
Since, Δ ABC ~ Δ EDF and Δ EDF ~ Δ GHI,
Therefore, Δ ABC ~ Δ EDF ~ Δ GHI,
Hence, the correct option is "Both"

Answers
Answer:
x=5
Step-by-step explanation:
Angles in a triangle adds up to 180 degrees
so 105 + (6x+20) + (7x-10) = 180
simplify
115+13x=180
subtract 115 to each side
13x=65
divide by 13
x=5
check work
105 + (6(5) + 20) + (7(5) -10)
105 + (30 +20) +(35 - 10)
105 + 50 + 25 = 180

Faye borrowed $9600 at 8% per anum compound interest.
(a) Calculate the interest on the loan for the first year.
At the end of the last year,she repaid $4368.
(b) How much did she still owe at the beginning of the year?
(c)Calculate the interest on the remaining balance for the second year.
Answers
Answer:
(a) $768
Step-by-step explanation:
Faye borrowed $9600 at 8% interest compounded per annum.
Solution for question (a):
Amount accumulated is given by;
A = P(1 + [tex]\frac{r}{n}[/tex][tex])^{nt}[/tex]
Where A is the amount, P is the pricipal, r is the rate, n is the number of times in a year, and t is the number of years.
So the amount after one year was;
A = 9600(1 + [tex]\frac{8}{1 * 100}[/tex][tex])^{1 * 1}[/tex] = 9600 × 1.08 = 10368
Interest = Amount - Principal = $10368 - $9600 = $768
a. The interest on the loan for the first year is $768.
b. The amount she still owe at the beginning of the year is $6,000.
c. The interest on the remaining balance for the second year is $480.
a. Interest on loan:
Interest on loan=$9600 × 8%
Interest on loan=$768
b. Amount owed
Amount owed=$9,600+$768-$4368
Amount owed=$6,000
c. Interest on remaining balance :
Interest on remaining balance=$6,000×8%
Interest on remaining balance=$480
Inconclusion the interest is $768, amount owe is $6,000 and Interest on remaining balance is $480.

when the fish swam down 55, you moved 55 to the left of zero. then when he swam 30 up, you take that 55 and move it 30 towards to the right. since -55 is greater than 30, your answer is still negative. -55+30=-25.

Answers
Answer:
The expressions for each statement are as follows:
a: 2500+(0.10*2500)
b: 40 * 0.85
c: 250 + (0.075*250)
Step-by-step explanation:
Part a:
Given
Salary = $2500
Percentage of raise = 10%
The new salary will be:
[tex]= 2500+ (10\%\ of\ 2500)\\=2500 + (0.10*2500)\\=2500+250\\=\$ 2750[/tex]
Part b:
Given
Total questions = 40
Percentage of correct answers = 85%
The required expression for correct answers is:
[tex]= 85\%\ of\ 40\\= 0.85*40\\=34[/tex]
Part c:
Given
Price of phone = $250
Percentage of sales tax = 7.5%
The required expression is:
[tex]Cost\ with\ sales\ tax = 250 + (7.5\%\ of\ 250) \\= 250 + (0.075*250)\\=250+18.75\\=268.75[/tex]
Hence,
The expressions for each statement are as follows:
a: 2500+(0.10*2500)
b: 40 * 0.85
c: 250 + (0.075*250)

Answers
The input value that gives an output of 19 is not listed in the answer choices. None of the options are correct.
What are the factors?A number or algebraic expression that evenly divides another number or expression—i.e., leaves no remainder—is referred to as a factor.
Here,
We can start by setting up the equation:
2x² + 3x + 5 = 19
Subtracting 19 from both sides:
2x² + 3x - 14 = 0
(2x - 7)(x + 2) = 0
Using the zero product property, we can solve for x:
2x - 7 = 0 or x + 2 = 0
2x = 7 or x = -2
x = 7/2 or x = -2
Therefore, the input value could be either 7/2 or -2.
The answer choices do not include 7/2, but we can check both input values to see which one gives an output of 19:
f(7/2) = 2(7/2)^²+ 3(7/2) + 5 = 19.25
f(-2) = 2(-2)² + 3(-2) + 5 = 3
Thus, the input value that gives an output of 19 is not listed in the answer choices.

Solve the triangle.
B = 36°, a = 41, c = 20
choices:
b ≈ 27.5, C ≈ 115.5, A ≈ 28.5
b ≈ 45.3, C ≈ 25.5, A ≈ 118.5
b ≈ 45.3, C ≈ 29.5, A ≈ 114.5
b ≈ 27.5, C ≈ 25.5, A ≈ 118.5
Answers
The triangle solve for B = 36°, a = 41, c = 20 is:
b ≈ 27.5, C ≈ 115.5, A ≈ 28.5
TriangleTo solve the triangle, we can use the Law of Cosines, which states that for any triangle with sides a, b, and c and angles A, B, and C opposite those sides,
c² = a² + b² - 2ab cos(C)
We can use this formula to find the length of the missing side b:
b² = a² + c² - 2ac cos(B)
b² = 41² + 20² - 2(41)(20) cos(36°)
b² ≈ 1074.12
b ≈ 32.8
Now that we have found the length of side b, we can use the Law of Sines to find the measures of angles A and C:
sin(A) / a = sin(B) / b
sin(A) / 41 = sin(36°) / 32.8
sin(A) ≈ 0.274
A ≈ 16.5°
We know that the angles in a triangle add up to 180°, so C = 180° - A - B ≈ 127.5°.
The closest choice to these values is:
b ≈ 27.5, C ≈ 115.5, A ≈ 28.5
