Question

Can someone help me with this

Answer 1

107

Explanation:

triangle angles = 180

31 + 42 = 73

180 - 73 = 107

Answer 2

The definition of a triangle is a polynomial with 3 sides and interior angles adding up to 180.

Using the definition, we can create an equation.

`180=42+31+x`

`180=73+x`

`x=107`

The measure of the third interior angle is 107 degrees.

Hope this helps.
