The third angle is #70# degrees.

The sum of the three interior angles of a triangle is #180# degrees.

The first angle is #-># #35# degrees.

The second angle is #-># #75# degrees.

Let the third angle be #x# degrees.

So,

#35+75+x=180#

#110+x=180#

Subtract #110# from both sides.

#x+110-color(red)110=180-color(red)110#

#x=70#

Therefore the third angle is #70# degrees.
