Answer:
x = 24.571
Step-by-step explanation:
A circles angle is 360 degrees, so you can work out x by equalling everything to 360
360 = 5x + 12 + 9x + 4
360 = 14x + 16
360 - 16 = 344
344 = 14x
344 ÷ 14 = 24.571
x = 24.571
So the smaller angle is 225°
And the bigger angle is 135°
(I'm guessing shape isn't to scale)
