Proving triangle similarity given QR PT and QPR STR prove PQR TSR
The triangles are right triangles, then we can apply Pytagoras´ theorem.
Solution is:
The triangles are similar
From the attached picture, and from parameterization concepts
RS = μ × RQ 0 < μ < 1
From Δ PRQ sinα = RQ/PR PQ = h₁ ( hypothenuse in Δ PRQ)
From Δ RST sinα = RS/ST ST = h₂ ( hypothenuse in Δ RST)
Then RQ/h₁ = RS/h₂
or RQ × h₂ = RS × h₁ ⇒ h₂ = (RS/RQ) × h₁ ⇒ h₂ = μ × h₁
Then both hypothenuse are proportional, it follows both triangles are similar

Answer:
12.6
Step-by-step explanation:
Given
with reference angle 57°
perpendicular (p) = y
hypotenuse (h) = 15
Now
sin 57° = p / h
0.84 = y / 15
y = 0.84 * 15

how to solve a problem like 5x-1-9x=6x-4
Answer: -10x=-3
Step-by-step explanation:
Answer:
3/10
Step-by-step explanation:
First you have to start by combining like terms. On the left side of the equations we can combine the like terms 5x and -9x to get -4x
Now the equation is -4x-1=6x-4 Now solve for x
Add 4x to both sides -1=10x-4
Add 4 to both sides 3=10x
Divide both sides by 10 x=3/10

What is the solution to this equation?
Answer:
x = - [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Given
4x - 6 = 10x - 3 ( subtract 10x from both sides )
- 6x - 6 = - 3 ( add 6 to both sides )
- 6x = 3 ( divide both sides by - 6 )
x = [tex]\frac{3}{-6}[/tex] = - [tex]\frac{1}{2}[/tex]

In the diagram if AE = AB, find the area shaded.
Answer:
Area shaded = 60 [tex]cm^{2}[/tex].
Step-by-step explanation:
From the given diagram,
Area shaded = Area of the trapezoid EBCD
Given that: AE = [tex]\frac{1}{3}[/tex]AB
= [tex]\frac{1}{3}[/tex] x 12 (∵ AB = CD = 12 cm)
= 4 cm
AE = 4 cm,
Thus,
EB = (12 - 4) cm
= 8 cm
EB = 8 cm
Area shaded = [tex]\frac{1}{2}[/tex] (EB + CD) x AD
= [tex]\frac{1}{2}[/tex] (8 + 12) x 6
= (20) x 3
= 60
Area shaded = 60 [tex]cm^{2}[/tex]

Answer:
a)16.32 rounded to the nearest whole number is 16 feet per second? True
b) 16.32 rounded to the nearest tenth is 16.3.? True
c) 16.32 rounded to the nearest hundredth is 16.33. ? False
Step-by-step explanation:
Select True or False for each statement.
a) 16.32 rounded to the nearest whole number is 16 feet per second. ?
16.32 to nearest whole number = 16 feet per second. This statement above is true.
b) 16.32 rounded to the nearest tenth is 16.3. ?
The number in the tenth position is 3, the number after it is 2.
Hence, 16.32 to the nearest tenth = 16.3
Hence, the above statement is true.
c) 16.32 rounded to the nearest hundredth is 16.33. ?
The number in the hundredth position is 2. There is no number after 2.
Hence,
16.32 to the nearest hundredth is 16.32
Hence, 16.32 rounded to the nearest hundredth is 16.33 is a false statement.

Find the difference 0.2 - 0.05 =
Answer:
0.2-0.05=0.15
Step-by-step explanation:
0.2=0.20
0.20-0.05=0.15
The required difference between 0.2 and 0.05 is 0.15, which is determined by the subtraction operation.
To find the difference between 0.2 and 0.05, we subtract 0.05 from 0.2:
0.2 - 0.05 = 0.15
The difference between 0.2 and 0.05 is 0.15.
When subtracting decimals, we align the decimal points and subtract each place value. In this case, both numbers have one decimal place, so we subtract the tenth place.
Starting from the right, we have 0 in the tenth place of 0.2 and 0 in the tenth place of 0.05. Subtracting 0 from 0 gives us 0.
Therefore, the difference in the tenth place is 0.
Since there are no other place values to subtract, the resulting difference is 0.15.

7/2x + 1/2x = 10 + 9/2x
Answer:
x=-1/20
Step-by-step explanation:
7/2x+1/2x=10+9/2x
We move all terms to the left:
7/2x+1/2x-(10+9/2x)=0
Domain of the equation: 2x!=0
x!=0/2
x!=0
x∈R
Domain of the equation: 2x)!=0
x!=0/1
x!=0
x∈R
We add all the numbers together, and all the variables
7/2x+1/2x-(9/2x+10)=0
We get rid of parentheses
7/2x+1/2x-9/2x-10=0
We multiply all the terms by the denominator

Select all equations that have graphs with the same y-intercept.
y = 3x - 8
y = 3x - 9
y = 3x + 8
y = 5x - 8
y = 2x - 8
y = (1/3)x - 8
The equations that have graphs with the same y-intercept are:
y = 3x - 8y = 5x - 8y = 2x - 8y = (1/3)x - 8To determine which equations have graphs with the same y-intercept, we need to look for equations that have the same constant term when written in the form y = mx + b, where m represents the slope and b represents the y-intercept.
The y-intercept is the value of y when x is equal to 0. In other words, it is the point where the graph intersects the y-axis.
Let's compare the equations and their constant terms:
y = 3x - 8 (Constant term: -8)
y = 3x - 9 (Constant term: -9)
y = 3x + 8 (Constant term: 8)
y = 5x - 8 (Constant term: -8)
y = 2x - 8 (Constant term: -8)
y = (1/3)x - 8 (Constant term: -8)
From the comparison, we can see that the equations y = 3x - 8, y = 5x - 8, y = 2x - 8, and y = (1/3)x - 8 all have the same constant term of -8. This means that their graphs will have the same y-intercept, which is -8.
Therefore, the equations that have graphs with the same y-intercept are:
y = 3x - 8
y = 5x - 8
y = 2x - 8
y = (1/3)x - 8
