Assume that we have two sides and we want to find all angles. The sides of a triangle are in arithmetic sequence and the greatest angle is double the smallest angle. ASA (angle-side-angle) - having the measurements of two angles and the side which serves as an arm for both (is between them), you can fully solve the triangle. Cosine Rule use these two for non right angled triangles Remember also your angle facts such as angles in a triangle equal 180° Example 1. Enter values three of the six sides and angles of the triangle and the other three values will be computed. See the non-right angled triangle given here. They use this knowledge to solve complex problems involving triangular shapes. To find the elevation of the aircraft, we first find the distance from one station to the aircraft, such as the side a, and then use right triangle relationships to find the height of the aircraft, h. Because the angles in the triangle add up to 180 degrees, the unknown angle must be 180°−15°−35°=130°.
