Can you do this please​
dezoksy [38]

Answer:

x = 24

Step-by-step explanation:

ABCD is a parallelogram.

Angle B and Angle C are adjacent (successive) angles.

Adjacent angles of a parallelogram are supplementary.

Therefore,

(5x) \degree + (2x + 12) \degree = 180 \degree \\  \\ (5x + 2x + 12) \degree = 180 \degree \\  \\ (7x+ 12) \degree = 180 \degree \\  \\7x+ 12 = 180 \\  \\7x = 180 - 12 \\  \\ 7x = 168 \\  \\ x =  \frac{168}{7}  \\  \\ x = 24
