Question

3) In a parallelogram MAIN, ∠M = (5x – 20)⁰ and ∠A = (3x + 40)⁰, the maximum value

of sum of opposite angles will be ___________

(A) 180⁰
(B) 200⁰
(C) 160⁰
(D) 100⁰​

Answer 1

(5x- 20) =( 3x+40)°

5x-3x= 40+20

2x=60

x = 60/2

x= 30

5x-20= 5×30-20=150-20=130

3x+40=3×30+40=90+40=130.

= 260°
