Answer:
x is 70
Step-by-step explanation:
I've tried to solve it as easy as I could. if you still need help you can ask
x = 50°
The sum of exterior angles in any polygon is 360°. X is an exterior angle, so to find x, we must form the equation x+70+90+60+90=360
We can simplify it and solve the equation as follows:
x+310=360
x=50
