Answer:
x = 30.
Step-by-step explanation:
For the triangles to be similar corresponding sides must be in the same ratio.
So 50/ 75 = x / 45
75x = 50*45
x = 50* 45/75
= 2 * 45 / 3
= 30. (answer).

Answer:
scale factor = 2
Step-by-step explanation:
The scale factor is the ratio of corresponding sides, image to original
C'D' = 6 and CD = 3 then
scale factor = 
= 2
Answer:
A) 41.9
Step-by-step explanation:
The formula I use is π(pi)r(radius)^2h(height)/3, so it looks like πr^2(h/3) and I used that and I got 41.88 which rounds to 41.9 or A
