Question

Angel A and B are complementary angel .If angle A is (x-20) and B is (x-30) .Find the measure of both angle.​

Answer 1

ANSWER:

Angle A = 80

Angle B = 100

Step-by-step explanation:

let angle A be X

then angle B is X plus 20

A. T. Q.

X plus X plus 20 =180

2x + 20= 180

2x = 180-20

X = 160/2

X =80

Answer 2

Step-by-step explanation:

x - 20 + x - 30 = 90

2x - 50 = 90

2x = 90 + 50

2x = 140

x = 140/2

x = 70°

A = 70 - 20 = 50°

B = 70 - 30 = 40°
