Question

A scalene triangle has an angle that measures 47∘ and a second angle that measures 88∘. What is the measure of the third angle?

Answer 1

45

Explanation:

In a triangle the angles add up to 180 degrees. So, we can subtract 47 and 88 from 180. The result, 45, will be your final answer.

Answer 2

45°

Explanation:

The angles of any triangle add up to 180 degrees

add the two known angles: 47+88=135

then subtract the sum from 180 to get answer: 180-135=45
