Description

Describe what this variable represents, and list any assumptions made about its value.

Can an exam override the value of this variable?

Generated value: `integer`

→ Used by:

This variable doesn't seem to be used anywhere.

Advice

The hypotenuse can be found by using Pythagoras' Theorem: $c^2 = a^2 + b^2$, so here $c = \sqrt{\var{a}^2 + \var{b}^2}$.

Then use the definition of the appropriate trigonometric function to find the correct ratio.
