What is the height of the ramp to the nearest foot?

The ramp is 6 ft tall

Step-by-step explanation:

We will call the height of the ramp h

sin theta = opposite side/ hypotenuse

sin 30 = h/12

Multiply each side by 12

12 sin 30 = h

6 = h

The ramp is 6 ft tall

6 feet.

Step-by-step explanation:

You can observe the the triangle shown in the figure attached is a right triangle, therefore, you can calculate the height of the triangle  (which you can call h) as following:

Where:

Substitute values and solve for the height. Therefor, the result is:

Then the height of the ramp is 6 feet.
