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!
Hello :)
Rule: Q = S
Rule: T + S = R + Q = 180
3x+5+9x-17 = 180
12x -12 = 180
Have a nice day :)
