Exercise 30 Page 380

Use the results of the previous exercise.

m∠ ACD=44

Practice makes perfect

In the previous exercise, we have shown that m∠ CAD = m∠ ACD and we found that m∠ CAD=44^(∘). Thus, we can immediately find m∠ ACD.

m∠ CAD = m∠ ACD

m∠ CAD= 44

44=m∠ ACD

Rearrange equation

m∠ ACD=44
