Jane and mark each build ramps to jump their remote controlled cars. both ramps are right triangles when viewed from the side. the incline of jands ramp makes a 30 dregree angle with the ground and the length of the incline ramp is 14 inches. the incline of marks ramp makes a 45 degree angle with the ground and the length of the incline ramp is 10 inches. what is the horizontal length of the base of janes ramp

1. You have that J ane's ramp makes a 30 dregree angle with the ground and the length of the incline ramp is 14 inches.

2. Then, to solve this problem you must apply the proccedure shown below:

Cos α=adjacent/hypotenuse

α=30°

adjacent=x

hypotenuse=14 inches

3. When you substitute the values and clear "x", you obtain:

Cos (30°) = x/14

x=14 (Cos30°)

x=124,70

4. Therefore, the horizontal length of the base of jane's ramp is:

124,70 inches
