Question

In parallelogram ABCD, m A = (5x – 20)° and m2C = (3x + 40). Find the value of x,​

Answer 1

Answer:

x = 20°

Step-by-step explanation:

Given, ABCD is a parallelogram (||gm)

∠A = (3x + 40)°

∠C = (5x - 20)°

∵ Co - interior angle is 180°

∴ ∠C + ∠A = 180°

=> (5x - 20)° + (3x + 40)° = 180°

=> 8x + 20° = 180°

=> 8x = 180° - 20°

=> 8x = 160°

=> x = 20°

∴ The value of x = 20°
