A young college student was working hard in an upper-level math course, for fear that he would be unable to pass. On the night before the final, he studied so long that he overslept the morning of the test. Trigometric Ratios We can use Pythagoras' Theorem see above to calculate the length of an unknown side in a right-angled triangle when we are given information about the lengths of 2 other sides.

## MATH 20 SAMPLE QUESTIONS

However, if we are given information about an angle other than the 90 degrees and one side and need to calculate the length of another side then we use the trig ratios. This first tutorial takes you through naming the sides of a triangle and an introduction to the trig ratios.

This tutorial is suitable for students in Year 10 or We can use trig ratios to calulate the length of a side on a triangle if we know the length of one side and the size of one angle.

You will need a scientific calculator for this tutorial This tutorial is suitable for students in Year 11 or Calculating angles using the trigometric ratios.

## Math Word Problems

OK, so probably saw this coming. If you know the length of the two sides of a right-angle triangle then you can caculate the size of the other angles inside the triangle.
