I believe it would be -17 degrees per minute
General rule: The angles on a straight line total 180°
The right angle equates to 90°
Since that angle is half of our desired angle, it must mean that 2x + x = 90°
breaking this down, we get 3x = 90° which can be divided to make x = 30°
Step-by-step explanation:
3x + 4 + 2x +7
= 3x + 2x + 4 + 7
= 5x + 11
