This page delves into more complex bearing calculations, including return bearings and multi-step problems.
Example: A walker travels 1200 m on a bearing of 165° and then another 1500 m on a bearing of 210°. The problem asks to find the distance from the starting point and the bearing to return to base.
The page demonstrates how to use scale drawings and trigonometric calculations to solve such problems. It introduces the concept of supplementary angles and the use of the cosine rule for non-right-angled triangles.
Highlight: When solving complex bearing problems, you may need to use Pythagoras theorem for right-angled triangles or the cosine rule for non-right-angled triangles.
This section is particularly useful for students preparing for trigonometry bearings questions and answers pdf and GCSE maths bearings and distance problems with solutions.
This page focuses on using the cosine rule to solve a complex bearing problem.
Definition: Cosine Rule: a² = b² + c² - 2bc cos A, where A is the angle opposite side a in a triangle.
The page provides a step-by-step solution to find the return bearing in the walker problem introduced on the previous page. It demonstrates how to set up the cosine rule equation, solve for the angle, and then use this information to calculate the final bearing.
Highlight: To find a return bearing, subtract the calculated angle from 360°.
This detailed explanation is invaluable for students working on bearings Maths GCSE questions and answers and IGCSE bearing questions and answers PDF.
The final page presents two complex bearing problems that integrate various concepts covered in the previous pages.
Problem 1 involves a coastguard spotting a boat and a tree, requiring students to draw a scale diagram and use Pythagoras theorem to verify their measurements.
Example: A coastguard spots a boat on a bearing of 040° and at a distance of 350 m. He can also see a tree due east of him. The tree is due south of the boat.
Problem 2 is a more complex scenario involving four towns and their relative positions using bearings and distances.
Highlight: When solving multi-step bearing problems, choose an appropriate scale for your diagram to ensure accuracy in measurements.
These problems provide excellent practice for students preparing for GCSE maths bearings and distance problems worksheets and measuring bearings using angles GCSE questions and answers.
This page introduces the fundamental concepts of bearings in mathematics.
Definition: Bearings are always measured from a North line clockwise and are given as 3-digit numbers.
Example: 18° is written as 018° in bearing notation.
The page explains how to calculate bearings in various diagrams, emphasizing the importance of drawing a North line when it's not provided. It also covers the concept of allied angles and angles around a point.
Highlight: To find a bearing, remember that angles around a point add up to 360°, and allied angles add up to 180°.
Vocabulary: Allied angles - Two angles that add up to 180°.
This information is crucial for students tackling bearings GCSE maths grade 8 questions and answers.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

Just amazing. Let's me revise 10x better, this app is a quick 10/10. I highly recommend it to anyone. I can watch and search for notes. I can save them in the subject folder. I can revise it any time when I come back. If you haven't tried this app, you're really missing out.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

very reliable app to help and grow your ideas of Maths, English and other related topics in your works. please use this app if your struggling in areas, this app is key for that. wish I'd of done a review before. and it's also free so don't worry about that.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.
