Question

A side of the triangle below has been extended to form an exterior angle of 70°. Find
the value of x.

Answer 1

The exterior angle and x form a straight line which need to equal 180.

x = 180-70 - 110

Answer: x = 110

Answer 2

Answer:

the exterior angle to 70 degrees is 110

Step-by-step explanation:

180-70 = 110

x= 110

but the last angle inside the triangle is 22

180-110=70-48=22
