Hello, kerilynn!

Did you make a sketch?

In parallelogram ABCD: .AB = 2x + 5, ./BAC = 2y, ./B = 120°, ./CAD = 21°, .CD = 21

Find x and y.Code:B *-----------------* C / 120° * / / * / 2x+5 / * / 21 / 2y * / / * 21° / A *-----------------* D

Opposite sides of a parallelgram are equal.

. . Hence: .2x + 5 .= .21 . → . x = 8

Adjacent angles of a parallelogram are supplementary.

. . Hence: .(2y + 21°) + 120° .= .180° . → . y = 19.5°
