Question

Find the angle measure x.
​

Answer 1

Answer:

we know that this is a quadrilateral

in a quadrilateral the sum of all angles is equal to 360°

to find the value of x we will add all the the angles and equal it to 360°

50° + 130° + 120° + x = 360°

300° + x = 360°

x = 360° - 300°

x = 60°
