Question

Given: ABCD is a parallelogram.

A = x + 30°; and

D = 2x + 60°. Find the angle measures.

Answer 1

because ABCD is a parallelogram,A+D= 180°;

Answer 2

x+30=2x+60 {opposite angles}

Answer 3

ok, but i need to find x

Answer 4

A and D have both x

Answer 5

does x =90?

Answer 6

A+D=A+D= 180°; then use A = x + 30°; and

D = 2x + 60°

Answer 7

yes, that comes out to 2x+60+4x+120=180

Answer 8

6x=0

Answer 9

A+D=180,

Answer 10

I just wrote A+D=A+D

Answer 11

oh, so it would be x+30+2x+60=180

Answer 12

3x=90

Answer 13

Good job

Answer 14

x=30

Answer 15
