How do you find the length of a leg of an isosceles right triangle?

Answer:

45 degrees

Step-by-step explanation:

BD bisects the angle so divide it by two

Answer:

The right answer is 45 degrees .

Answer:

21

Step-by-step explanation:

I think its 21, because the BD line divides the big triangle into 2 ones and they are equilateral triangle, sorry if I'm wrong

Answer:

BD = 21

Step-by-step explanation:

The sector divided AC into two equal pieces and since this is a right triangle the height of the triangle BD is equal to half of the base

(21+21) / 2 = x

42 / 2 = x

21 = x

Answer:

27 degrees

Step-by-step explanation:

So looking at this rhombus, we can make out 4 seperate traingles.

How many degrees are in a traingle? 180.

Looking at the traingle with z angle in it, we can see that it is a right traingle.

Now, lets subtract that 90 degrees from the 180.

This leaves us with the 63 degrees and x that make up the 90 degrees that are left.

Now all we have to do is subtract the 63 degrees from the 90 total degrees that we have left, and we will find out what z is equal to.

90 minus 63 is 27, so the angle of z is:

27 degrees

I hope this helps!

Note that I assumed these are right traingles, however I dont see how you can solve this without these being right trianlges, since you cannot use sin, cos, or tan to find this value without another angle or side length.

[tex](17^{1/7} )^{7}[/tex] = [tex]17^{1/7 * 7 }[/tex] = [tex]17^{1}[/tex] = 17

hope this answer helps you.....

Answer:

17

Step-by-step explanation:

[tex](17^{\frac{1}{7} })^{7} = 17^{\frac{1}{7} } 17^{\frac{1}{7} } 17^{\frac{1}{7} }17^{\frac{1}{7} }17^{\frac{1}{7} }17^{\frac{1}{7} }17^{\frac{1}{7} } = 17^{\frac{1}{7}+\frac{1}{7} +\frac{1}{7}+\frac{1}{7}+\frac{1}{7}+\frac{1}{7}+\frac{1}{7} }=17^{\frac{7}{7} } =17^{1} = 17[/tex]

Answer:

7.9

Step-by-step explanation:

the first thing to do is find the second projection.

16-7 = 9

than we can use a proportion to find BD

7 : BD = BD : 9

BD = √9 x 7 = √63 = 7.9

we have to use the square root because in the proportion BD Is repeated two times. If we don’t use it, we find BD^2

Answer:

3x-8

Step-by-step explanation:

15x^2 - 22x - 48 / 5x + 6

15x^2 / 5x = 3x

-48 / 6 = -8

3x-8

Answer:

60+4.5pi

Step-by-step explanation:

6×10 obv + area of circle pi(r^2) and half that for a semi cirxle

Answer:

9 π^2

Step-by-step explanation:

Let's just fined the area of the rectangle: Area= 2lw = A=60

Now, we know the diameter of the Spehre which is 10 -2 -2 = 6, the radius is half of that = 3

A=πr2 = A≈28.27

add A≈28.27 + 60 = 88.27 = 9 π^2≈88.82643

Answer:

1, 0, 2, 3

Step-by-step explanation:

Answer:

1, 0, 2, 3

Step-by-step explanation:

Answer:

(-1, 3)

Step-by-step explanation:

In order for a point to be a solution to a system of equations, the lines have to intersect at that point in the graph. We can see that the two lines at the graph intersect at (-1,3), so that must be the solution.  

Answer:

2.26

Step-by-step explanation:

To round our answer to nearest hundredth, we will round our answer to 2 digits after decimal. We can see that thousandth value is less than 5 that is 3, so will keep last digit 6 as: Therefore, the decimal value of our given fraction is approximately 2.26 to the nearest hundredth.

Answer:

$7700

Step-by-step explanation:

Given data

Rate= 2%

Principal= $7000

Time= 5 years

The simple interest expression is

A=P(1+rt)

substitute

A=7000(1+0.02*5)

A=7000(1+0.1)

A=7000*1.1

A=7700

Hence the amount is $7700

Answer:

$4.3

Step-by-step explanation:

Cole bought 10 gallons of gas at the gas station with the lowest price.(the lowest price is $3.57 each gallon.) He paid with two $20 bills. Write and solve an equation to find his change.

two $20 bills = 2 * $20

= $40

Gallons of gas = 10

Lowest price of each gallon = $3.57

Cost of 10 gallons of gas = 10 * $3.57

= $35.7

Let his change = x

His change = Amount paid with - cost of gas

x = $40 - $35.7

x = $4.3

His change = $4.3

Answer:

Step-by-step explanation:

Answer:

x = ±1.155

Step-by-step explanation:

We need to graph the given function [tex]f(x) = 6x^2-11+3[/tex] and find its zeroes.

The attached figure shows the graph of the given function.

To find zeroes,

Put f(x) = 0

So,

[tex]6x^2-11+3=0\\\\x=\pm 1.155[/tex]

Hence, this is the required solution.

Answer:

The difference in both the guessed values is 5 unit

Step-by-step explanation:

The less error computation is done by dividing the difference between the guessed value and the actual value.

Here in this case

Error in case of Fransisco = 55-50 = 5

Error in case of Kazuko = 60 -55 = 5

Hence, both have guessed incorrect value and their incorrect values is either 5 units less or 5 units higher than the actual value.
