Question

In a parallelogram ABCD, angle B = (2x + 25)° and angle D = (4x – 5)°. Find:
(ii) measure of each of the remaining angle.
(i) the value of x​

Answer 1

Answer:

A.T.Q

2x+25=4x-5

30=2x

x=15

B=2*15+25=55°

D=4*15-5=55°

A=C

B=D

360°-B-D=A+C

360-55-55=A+C

360-110=A+C

250°=A+C

A=C

250°/2=A

125°=A

A=C

C=125°
