  1. Now, let’s see some of the examples.

  2. 1. In the diagram above, IJK and JML are straight lines. Given that tan x= 2, JL=14cm and IK= 10cm, calculate the length, in cm, of LM.

  3. Solution: In 7cm Given that, IK=10cm

  4. 3cm 7cm

  5. 2. In the diagram, KLM is a straight line. Which of the angles, A, B, C or D has a sine value of ?

  6. Remember,

  7. 3. In the diagram, QTS is a straight line and QT=3TS. Calculate the value of cos x.

  8. 12cm
