Question

Triangle CDE is similar to triangle FGH. Find the measure of side HF. Round your answer to the nearest tenth if necessary.

Answer 1

HF = 11.0

Explanation:

We can use a ratio to solve

ED EC

----- = ----------

HG HF

23 36

----- = ----------

7 HF

Using cross products

23 HF = 36*7

23 HF = 252

Divide by 23

HF = 252/23

HF =10.95652

To the nearest tenth

HF = 11.0
