6.1 Practice Assignment Find the measure of angle 1? pls help

Svetlanka [38]

Answer:

79 degrees

Step-by-step explanation:

First, you want to find the interor angles.

Since there are 180 degrees in a triangle...180-(27+52)=101 degrees

And the bottom line is a straight line so it's equal to 180 degrees as well.

180-101=79 degrees
