First, you can notice that the angle of 130 degrees and the angle next to it make up a line. So, they should add up to 180 degrees. We do 180-130 to get 50. So that angle next to 130 is 50 degrees. The interior angles of a triangle should add up to 180 degrees so let’s do 180-50 to get 130. The angles are equal to each other so we can just do 130/2 and get 65 degrees. Lastly, y=65 degrees.

Answer:
Length of the ramp = 18.6 feet (Approx.)
Step-by-step explanation:
Given:
Horizontal distance (base distance) = 17 feet
Angle of elevation = 24°
Find:
Length of the ramp
Computation:
Cosθ = Length of base / Length of hypotenuse
Cos 24 = Horizontal distance (base distance) / Length of the ramp
Cos 24 = 17 / Length of the ramp
0.9135 = 17 / Length of the ramp
Length of the ramp = 17 / 0.9135
Length of the ramp = 18.6 feet (Approx.)
Assuming you are trying to get price per pound.
Divide 750 by 5 which equal 150 or $1.50
