Question

Two angles of a triangle are 47 and 32 degrees. Select all angles that could represent exterior angles of a triangle.

Answer options:
101 degrees
79 degrees
152 degrees
133 degrees​

Answer 1

133, 79, 148 are ALL possible, so select 133 and 79

Explanation:

Subtract 47 and 32 from 180 to find the third angle of the triangle (it is 101).

Then do 180-101 = 79

180-32=148

180-47=133

That tells you the exterior angle of each. Only two possible choices on your list.
