27.3 Using tangent ratio to calculate angles and side (Tan = $\frac{o}{a} )$
Using tangent ratio to calculate angles and side (Tan = $\frac{o}{a} )$
Tangent ratio is yet another trigonometric ratio for rightangled triangles. Tangent ratio is the ratio of opposite side to adjacent side of a right triangle. Same as the sine and cosine ratios, tangent ratios can be used to calculate the angles and sides of right angle triangles.
