It's a beautiful day to go outside with a kite or a balloon, and compute how wind speed alters their flight.

A KS3 Bitesize Maths guide showing how to work out the value of different angles on a set of crossing lines.

We need to calculate it using our apparent-wind angle, apparent-wind speed, and boatspeed (speed through the water, not speed over ground).

Learn how to find the angles in right-angled triangles with this BBC Bitesize Maths article. For students between the ages of 11 and 14.

We all remember math class in grade school and being asked to calculate angles for a geometry chapter. Well, while you might not have realized … ...
