The third angle is 7070 degrees.

Explanation:

The sum of the three interior angles of a triangle is 180180 degrees.

The first angle is -> 3535 degrees.

The second angle is -> 7575 degrees.

Let the third angle be xx degrees.

So,

35+75+x=18035+75+x=180

110+x=180110+x=180

Subtract 110110 from both sides.

x+110-color(red)110=180-color(red)110x+110110=180110

x=70x=70

Therefore the third angle is 7070 degrees.
