How to determine angles in a triangle
WebMay 9, 2024 · 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 \(180°−15°−35°=130°\). WebMar 20, 2024 · An external angle is added to the inner angle of the triangle to which it is adjacent. The interior angles of a triangle sum up to 180 degrees. Therefore, multiply the number of triangles in the polygon by 180° to determine the sum of internal angles.
