Answer:
D. 43 degrees
Step-by-step explanation:
The sum of angles in a triangle is 180°. If x represents the measure of the third angle, then ...
75° +62° +x = 180°
137° +x = 180° . . . . . . . . . collect terms
x = 180° -137° = 43° . . . . subtract 137° from both sides of the equation
The third angle measures 43°.
