Answer: 44°
Step-by-step explanation:
Measures of the angles of a triangle
= 180°
Therefore, 180 - 105 + 31 = 44°
First you add the two angles of the triangle to get 136
You then subtract this from 180 because all the angles in a triangle add up to 180
The third angle= 44 degrees
You then subtract this from 180 because all the angles in a triangle add up to 180
The third angle= 44 degrees
