Answer 1

Answer:

HEY BRO HERE'S YOUR ANSWER

Given:

A + C = 120°. -(1)

B + C = 40°. -(2)

A + B = 100°. -(3)

Step-by-step explanation:

FROM (1)

A + C = 120°

A = 120° - C. -(4)

FROM (2)

B + C = 40°

B = 40° - C. -(5)

FROM (3), (4) AND (5)

A + B = 100

(120 - C) + (40 - C) = 100

160 - 2C = 100

-2C = -60

C = 30

BY PUTTING VALUE OF C IN (1)

A + C = 120

A = 90

BY PUTTING VALUE OF C IN (2)

B + C = 40

B = 10
