This video is an example of answering a sine rule question … but, unfortunately, we aren’t given that information – you just need to spot that you’ve got two angles and one side:
Joe has a field in the form of a triangle ABC, with dimensions as shown.
(a) Calculate length AB
(b) The area of the field
The question is aimed at GCSE maths grade 7+ calculator paper.
I hope this video helps, and please do leave a comment below, thank you!
These types of questions appear in all the main examination boards, including Edexcel, AQA and OCR. They are popular and, once you have the basic principles, fairly similar. Please do stop the video, try the question and compare your solution!
I hope the video helps and please do leave a comment – thanks!
