Find the measure of the missing angle.

Answer: 50
Step-by-step explanation:
A right angle is 90 degrees. A triangle must add up to 180 degrees. Add 40 and 90 to get 130. Then subtract 180 from 130 to get 50.
Answer:
? = 50°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 angles from 180° for ?
? = 180° - (90 + 40)° = 180° - 130° = 50°
