Question

□ABCD is a parallelogram If angles A=4x+13 and angle D=5x-22 find the of angels B angels C
I

Answer 1

Step-by-step explanation:

Angle A + Angle D = 180 degree

4x+13+5x-22 = 180 degrees

9x - 9 = 180

x-1 = 180/9

x = 21 degrees

Angle A = 82+13

A = 95

A +B = 180

B = 180-95

B = 85 degrees

Angle D = 105-22

=83

C +D = 180

C = 180-83 = 97
