Question

Find the measure of the missing angle​

Answer 1

50

Explanation:

40 plus 90 equals 130 and triangle must be 180 so we need 50 degree

Answer 2

50°

Let x be the missing angle.

90°(right angle) + 40°(given) + x = 180° ( the sum of degrees of interior angles of triangle)

x = 180°-130°

x = 50°
