For a right angled triangle follow these steps to calculate the length of a side x when another side and an angle is given Label the two sides that contain information in the The sine rule can be used to find an angle from 3 sides and an angle or a side from 3 angles and a side The cosine rule can find a side from 2 sides and the included angle or an angle from
The Triangle Angle Calculator is a tool that calculates the angles of a triangle given the length of its sides To use the calculator the user simply inputs the length of the three sides of the triangle and the calculator will use the law of If you know two angle measures and a side length on a triangle you can use the Law of Sines to find the missing parts of the triangle In this case you need to know either two angles and the side in between them

For a right angled triangle follow these steps to calculate an angle when two sides are given Choose one of the three trigonometric ratios close trigonometric ratio A ratio Use The Law of Cosines first to calculate one of the angles then use The Law of Cosines again to find another angle and finally use angles of a triangle add to 180 to find the last angle We use the angle version of the Law of Cosines
But when you re solve sin B frac b sin A a there are two solutions that could be angles in a triangle B 1 arcsin left frac b sin A a right the one you found and B 2 180 We must use The Law of Cosines first to find any one of the three angles then we can use The Law of Sines or use The Law of Cosines again to find a second angle and finally Angles of
