Show answer. question 2: use the sine rule to find the side length marked x in the below triangle to 3 significant figures. [2 marks] level 6 7 gcse aqa edexcel ocr wjec cambridge igcse edexcel igcse. show answer. question 3: use the sine rule to find the obtuse angle x on the diagram below to 3 significant figures. A sin 45 = 8 sin 60. step #4: rearrange the formula so that the unknown side becomes the subject. we can rearrange the formula to isolate side a: a = 8 x sin 45 sin (60) step #5: replace the known sides with the values and solve for the unknown side. we can simplify the denominator of the sine function to get: a = 8 x sin 45 sin 60. a. Sult of ‘follow through’) m1 – this is a method mark. method marks have been shown in places where they might be awarde. for the method that is shown. if you use a different method to get a correct answer, then the same number of method marks would be awarded but it is not practical to show all possible methods, and the way in which marks.

To calculate the height of a church tower, a surveyor measures the angle of elevation of the top of the tower from two points 50 metres apart. the angles are shown in the diagram. 9. the angles of elevation of a hot air balloon from two points, a and b, on level ground, are 24 .2 ° and 46 .8 °, respectively. However, if we want to find a missing length or an angle in a non right angle triangle we use the sine and cosine rules. refer to fig 4. sine rule: we can use the sine rule to work out a missing length or an angle in a non right angle triangle, to use the sine rule we require opposites i.e one angle and its opposite length. the sine rule is.
