What’s the answer

Question

The two triangles pictured are similar. What is the length of y? *

1 point

A) 6.0

B) 7.0

C) 8.0

D) 9.0

Answer 1

1. If the triangles are similar, then the corresponding sides are similar too, and they form a proportion.
2. Just make sure to form the proportion the right way.
3. In simple words: bottom leg of big triangle over bottom leg of small triangle, and then right leg of big triangle over right leg of small triangle.

That means:

y / 1.0 = 24.5 / 3.5 divide 24.5 by 3.5

y / 1.0 = 7 anything divided by 1, is that same number so y divided by 1 is y, which means:

y=7

The answer is B.
