Answer:
All except the second one (angle g is not similar to angle r)
Step-by-step explanation:
Just look at the order of the letters. It it's the same, its similar.
P-6 because you subtract the variable from the 6
Before dilation:
the height of the triangle is h₁ = 7 - (-1) = 8
the width of the triangle is w₁ = 7 - (-5) = 12
After dilation:
the height of the is h₂ = 9-7 = 2
the width of the triangle is w₂ = -5 - (-8) = 3
The scale factor is h₂/h₁ = 2/8 = 1/4 = 0.25
Also, the scale factor is w₂/w₁ = 3/12 = 1/4 = 0.25
Answer: The scale factor is 0.25
Since the number before the number in the tenth place (7) is greater than 5 (8), you will be rounding up. So your answer is 9.80
