Question

Triangle B is a scale image of Triangle A as shown. Find the base of Triangle A in centimeters. Show your work. (please help! ive been stuck on this for a while!)​

Answer 1

13

Explanation:

We are given the sides of one of the triangles. If you take 9/40.5, you get .2222222. We can then use that to find the base. If you take 58.5, multiply it by .22222, you get 13!

Answer 2

? = 13

Explanation:

40.5/9 = 4.5

9 x 4.5 = 40.5

X x 4.5 = 58.5

4.5X = 58.5

4.5X/4.5 = 58.5/4.5

x = 13
