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

Answer:
HF = 11.0
Step-by-step 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
