WORKSHEET 6-6 TRIGONOMETRY YEAR TEN The hypotenuse of this rightangled triangle is fifteen metres long. The hypotenuse of this rightangled triangle is fifteen metres long. The hypotenuse of this rightangled triangle is fifteen metres long. The hypotenuse of this rightangled triangle is fifteen metres long. One angle in the right-angled triangle measures thirty degrees. One angle in the right-angled triangle measures thirty degrees. One angle in the right-angled triangle measures thirty degrees. One angle in the right-angled triangle measures thirty degrees. We are given an angle of thirty degrees and the hypotenuse of fifteen metres. We want to find the opposite. Therefore we know we need to use the sine ratio. We are given an angle of thirty degrees and the hypotenuse of fifteen metres. We want to find the opposite. Therefore we know we need to use the sine ratio. We are given an angle of thirty degrees and the hypotenuse of fifteen metres. We want to find the opposite. Therefore we know we need to use the sine ratio. We are given an angle of thirty degrees and the hypotenuse of fifteen metres. We want to find the opposite. Therefore we know we need to use the sine ratio. The length of the side labelled q is equal to fifteen times the sine of thirty degrees. The length of the side labelled q is equal to fifteen times the sine of thirty degrees. The length of the side labelled q is equal to fifteen times the sine of thirty degrees. The length of the side labelled q is equal to fifteen times the sine of thirty degrees. The length of q is equal to 0.5 times 15. The length of q is equal to 0.5 times 15. The length of q is equal to 0.5 times 15. The length of q is equal to 0.5 times 15. Therefore the length of q is equal to 7.5 metres. Therefore the length of q is equal to 7.5 metres. Therefore the length of q is equal to 7.5 metres. Therefore the length of q is equal to 7.5 metres.
