Question

BCD is a parallelogram. If angle B is equal to (2x)° and angle A is equal to (-x + 120)°, find x.


I got x=60. Is it correct?

Answer 1

the angles are equal it sounds like, opposite angles in a parallelogram

Answer 2

2x = -x+120

Answer 3

so you got it !

Answer 4

ABCD is a parallelogram. Sorry the A was missing.

Answer 5

wouldn't 2x = -x+120 give 40?

Answer 6

one sec---

Answer 7

\[2X+(-X+120)=180\]

Answer 8

they gonna add up to 180

Answer 9

So 2X+(−X+120)=180 = 2x-x+120 = 180
x+120=180
x=60??
