According to the information given, the ramp would be 50 feet high. (However, that seems really high. Did you type your problem correctly?)
If you draw a picture, you will see that you can set up a cosine ratio to solve this problem. With a 30 degree angle of depression, the angle we are going to use 60 degrees.
We can set up the following equation:
cos(60) = x / 100
0.5 = x / 100
50 = x
Answer:
315 m/s = 1134 km/h
Step-by-step explanation:
Multiply the speed value by 3.6
315 x 3.6 = 1134
To show equality with fractions both fractions should be converted to show their values with the same denominator then draw a picture of those fractions.
Remember that you can only compare fractions with the same denominator as is said with other operations dealing with fractions.
Any set of 3 points is "coplanar".
