Question

I’ve never understood how to solve these

Answer 1

111°

Explanation:

to solve for x, first find the unknown angle in the triangle.

let the unknown angle= y

48+63+y = 180(sum of angles in a triangle)

111+y = 180°

Y= 180-111

Y= 69°

TO FIND X

X+69= 180 (ANGLES ON A STRAIGHT LINE)

X= 180-69

X= 111°
