Answer 2

Answer:

105°

Explanation:

Two angles are linear if their angle measures add up to 180°. (This is also known as vertical angles.)

If we know the measure of one angle, we can easily find the measure of the other, assuming x is the missing angle:

$75 + x = 180\\\\x = 180-75\\\\x=105$

Hope this helped!
