Question

if the quadrilateral ABCD is a parallelogram what is the value of x​

Answer 1

Answer:

x=32

180*=5x+20

5x=180-20

5x=160

x=160/5

x=32//

Answer 2

Answer:

Sum of two adjacent angles of quadrilateral =180

Angle C + angle B = 180

(3x+3) + (2x+17 ). = 180

3x+3+2x+17 = 180

5x+20 =180

5x = 180 - 20

5x = 160

x = 160/5

x = 32

Step-by-step explanation:

Hence , Angle C => 3× 32+3

= 99°

Angle B = 2× 32 +16

= 81
