Hello :)

Rule: Q = S

Rule: T + S = R + Q = 180

3x+5+9x-17 = 180

12x -12 = 180

12x = 192

x = 16

Have a nice day :)

Hello!

➡This a parallelogram.

➡İnterior angle : 360

Rule:

S= Q

R = T

S + R = Q + T

S + R = 180

Q + T = 180 *

Q = 3x + 5

T = 9x - 17

3x + 5 + 9x - 17 = 180

3x + 9x + 5 - 17 = 180

12x - 12 = 180

12x = 180 + 12

12x = 192

12x/12 = 192/12

x = 16

Nice day!
