Answer:

(B) 70

Step-by-step explanation:

Complementary angles are angles whose measures sum up to 90

90-70 = 20

complement 1 = 70

complement 2 = 20

70-20 = 50

this means 70 is 50 greater than its complement

70 is the only angle - out of the options that fulfills the criteria of being 20 greater than its complement

Answer:

B

Step-by-step explanation:

Complementary angles sum to 90°

let the angle be x then its complement is (90 - x) , so

x = 90 - x + 50

x = - x + 140 ( add x to both sides )

2x = 140 ( divide both sides by 2 )

x = 70

The angle measure is 70°
