Question

In parallelogram ABCD, ∠A = (5 − 20)° and ∠ = (3 + 40)°. the value of .​

Answer 1

Answer:

A 80°

B 100°

Step-by-step explanation:

Opposite side of Parallelogram are Supplementary

So A + B = 180°

(5x-20) + (3x+40) = 180

so 5x+3x + 20 = 180

8x = 180 - 20

8x = 160

x = 20

Value of A (5x-20) = (5(20)-20) = 100 - 20 = 80

value of B (3x+40) = (3(20)+40) = 60 + 40 = 100
