What is the measure of angle 1?

A triangle has angles 29 degrees, 65 degrees, and 2. The exterior angle to angle 2 is 1.

86 degrees

Step-by-step explanation:

So what you do is that since a triangle is 180 degrees added together you first subtract 180-29 and then you get 151 and then you subtract 151-65 and that's how I got 86
