WebTrigonometry angles are the angles given by the ratios of the trigonometric functions. Trigonometry deals with the study of the relationship between angles and the sides of a triangle. The angle value ranges from 0-360 … WebLet us say the angle is θ, then. tan θ = Height/Distance between object & tree. Distance = Height/tan θ. Let us assume that distance is 30m and the angle formed is 45 degrees, then. Height = 30/tan 45°. Since, tan 45° = 1. So, Height = 30 m. The height of the tree can be found out by using basic trigonometry formulas.
