  1. Trigonometry

  2. Unit 4:Mathematics Aims • Jog your memory on Pythagoras therom and Trigonometry Objectives • Identify lengths and angles of right angle triangles using formulas.

  3. 15

  4. Right angled triangle hypotenuse opposite adjacent

  5. There are three ratios that you need to learn: hypotenuse opposite adjacent

  6. Finding a length You need to label all the lengths of the triangle. hypotenuse 10cm opposite The adjacent is not needed in this question; the question is only using opposite and hypotenuse. adjacent

  7. Finding a length You need to label all the lengths of the triangle. The adjacent is not needed in this question; the question is only using opposite and hypotenuse. hypotenuse 10cm opposite

  8. Finding a length hypotenuse 10cm opposite

  9. Finding a length hypotenuse 10cm opposite OR rearrange the equation (*) by multiplying both sides by x.

  10. These two triangles are very different. The variable xwill be on the denominator This is an example of where we have to solve an equation with the variable on the denominator, so multiply both sides by x. still need to get x on its own, so divide both sides by sin30

  11. 2. Pick the correct formula 1.Label the triangle 3.Substitute in the correct values 15cm opposite adjacent 4. Rearrange to find x

  12. 15cm opposite adjacent
