Question

What is the measure of DAC?

Answer 1

i'm sorry if i'm wrong but I believe it's 57

Explanation:

Answer 2

47 degrees

Explanation:

First let's find the measure of Angle CAB. We know that angles in a triangle add up to 180 so...

CAB+ACB+ABC=180

CAB+80+57=180

CAB+137=180

CAB=43

We also know that DAB is equivalent to 90 degrees as DAE and DAB are a linear pair which means they add up to 180 degrees. Since DAE is a right angle, DAB also has to be a right angle.

We can use DAB and CAB to find DAC:

DAC+CAB=DAB

DAC+43=90

DAC=47 degrees
