Question

Find measure of angle D

Answer 1

Hello there,


So the first thing that we are going to do is add the the measurement's together.

105°+95°+80°=360°.

We need to find out what equal's 360.

So were going to do 280+ x = 360.

The way a found that out was 280-360=80.

80° would be your correct answer.

Hope this helps.
