To answer this question, you need trigonometry.

Are you familiar with the chant soh cah toa?

In here, you can see that the side you have is adjacent to the angle you have, and you're trying to find the opposite side. This means you need tangent = opposite ÷ adjacent

If the angle was 30° 45° or 60° Then there is a table you can use to calculate, but there isn't so just use a calculator

tan 31° = x ÷ 10

We have an angle and an adjacent side, and we are looking for an opposite side. Because we have adjacent and opposite, that tells us that we need to use tangent.

10 * tan(31) = 6.008, when rounded to the nearest tenth you would just say 6.
