Answer:
49 inches
Step-by-step explanation:
To obtain the height, h of the ramp ;; we use trigonometry ;
h = opposite and the value of the hypotenus :
Sin θ = opposite / hypotenus
Sin 22 = h / 132
h = 132 * sin 22
h = 132 * 0.3746065
h = 49.44
Height of ramp = 49 inches
For the truth

Answer:
BC = 12, AC = 12, ED = 8, DK = 14, EK = 12
When we add the angle that has x° and the angle that has (4x-20)° we need to get 180°.
Mathematically: x° + (4x-20)° = 180°.
We solve for x:
x°+4x°-20°=180°, we put all numbers that we know on the right side and all unknowns on the left side:
5x°=200°, we divide by 5 and get:
x=40°
So the correct answer is D. x=40°.
