To find the measure of the missing angle in the triangle, we need to use the fact that the sum of the angles in a triangle is always 180°.
So, the sum of the two given angles is 103° + 40° = 143°.
To find the measure of the missing angle, we subtract the sum of the two given angles from 180°:
180° - 143° = 37°
Therefore, the missing angle in the triangle is 37°.
A triangle has two angle measures of 103° and 40°. What is the measure of the missing angle?
