Question

Find the value of x.

Answer 1

In a triangle:

Exterior angle = Sum of opposite interior angles.

110 = x + 60

x + 60 = 110

x = 110 - 60

x = 50

x = 50 degrees.

I hope this helped.

Answer 2

the value of the external angle is equal to the sum of the other 2 opostite internal angles

this means that
110=x+60
minus 60 both sides
50=x
x=50 degreees
