Answer 1

Answer:

Given:

∠DAB = (5x + 20)°

∠BCE = (5x + 10)°

Solution:

In parallelogram ABCD,

∠DAB = ∠DCB (Opposite angles in a

∠ADC = ∠CBA parallelogram are equal)

∠DAB = ∠DCB = (5x + 20)°

Now,

∠DCB + ∠BCE = 180° (Linear pair)

(5x + 20)° + (5x + 10)° = 180°

5x + 20° + 5x + 10° = 180°

10x + 30° = 180°

10x = 180° - 30°

10x = 150°

x = 150°/10

x = 15

Therefore, the value of x is 15.
