Question

In a parallelogram,ABCD,IF measure angle A=(3x+12°),measure angle B =(2x-32°),then find the value of x and also find the measures of angle C and D​

Answer 1

A+B=180° (adjacent angles)

3x+12+2x-32=180

5x-20=180

5x=200

x=40

A=120+12

A=C=132 (opp. angle of llgm)

B=80-32

B=D=48 (opp. angle of llgm)
