Answer:

About 9.1 yards tall.

Step-by-step explanation:

So, we can draw the right triangle shown below:

We want to find h.

Since we know the angle and the side adjacent to the angle and we wan to find the opposite side, we will use the tangent ratio:

\displaystyle \tan(x^\circ)=\frac{\text{Opposite}}{\text{Adjacent}}

So:

\displaystyle \tan(20)=\frac{h}{25}

Therefore:

\displaystyle h=25\tan(20)

Use a calculator. Ensure your calculator is in the correct mode (degrees mode):

h\approx 9.1\text{ yards}

The goal post is around 9.1 yards tall.
