Question

What is the value of x.

Answer 1

x = 47

Explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

121° is an exterior angle of the triangle, then

x + 74 = 121 ( subtract 74 from both sides )

x = 47

Answer 2

x=47

Explanation:

180-121=59

180-(59+74)=47
