Question

What is the measure of angle TGF?

A
28 degrees
B
58 degrees
C
86 degrees
D
94 degrees

Answer 1

C

Explanation:

Sum of angles in triangle is 180 degrees.

28°+58°+ x= 180 degrees

x=94 degrees

sum of angles on a straight line is 180 degrees

thus, 94 degrees + ? = 180 degrees

?= 86 degrees

angle TGF is 86 degrees
