1 ABCD is a parallelogram. If angle A = (4x+13)" and angle D=(5x-22)° then find the measure of x
Sol:- angle A and angle D are adjacent angles
Adjacent angles of a parallelogram are ________
(4x + 13)° + (5x-22)°=_______
_______ + _______ = 180
9x = 189
x = _______​

Answer 1

Answer:

May help you :)

Step-by-step explanation:

Adjacent angles of a parallelogram are supplementary

(4x+13) + (5x-22) = 180

9x + (-9) = 180

9x = 189

x = 189/9

x = 21

Answer 2

ABCD is a parallelogram .

angle A=(4x+13) and angle D=(5x-22)

Above ur answer here i hope it help you
