A triangle in total is 360<span>°. So you add what you are given
46 + 61 = 107
and subtract that from 360
360 - 170 = 190
And the remainder is the last unknown angle.
So, the third angle is 190</span><span>°</span>

The image I saw was a paper with 90° edges. the 90° was cut into 2, 75° and x.
x = 90° - 75° = 15°
Interior angles of a triangle should equal 180°. The other corner of the paper is part of the triangle. It has a measure of 90°
The two angles are 15° and 90°. To find the remaining unknown angle, we deduct the two angles from 180°
3rd angle = 180° - 15° - 90°
3rd angle = 180° - 105°
3rd angle = 75°
