MEP Y9 Practice Book B 158 Example 1 Calculate the length of the side marked x in this triangle. Solution In this question we use the opposite side and the hypotenuse. These two sides appear in the formula for sinθ, so we begin with, sinθ= O H In this case this gives, sin 40 °= x 8 or x =840×°sin =5.142300877 cm =5.1 cm to 1 decimal place ...
