I believe that B is the answer bc -2-1 is -3 but with absolute value it it's 3, whish is the correct distance
sketch the situation
a trigonometric function that is a relation between the angle of elevation and the 2 sides of the rectangles is the tan


find the inverse

after rounding the angle of elevation is 34º.
It's 14.285714%
So, simplified it would be 14.3% because you round the 2 up since theres an 8 behind it.
