Expert Solution

Step 1

We have to clarify about the formula for trigonometric ratio of tangent or tan ratio

tan ratio is the ratio of perpendicular to the base

in right angle triangle there are three sides perpendicular, base and hypotenuse

these are denoted by:

$\begin{array}{rcl} p e r p e n d i c u l a r & = & p \\ b a s e & = & b \\ h y p o t e n u s e & = & h \end{array}$

Relation between these are established by Pythagoras,

$h^{2} = p^{2} + b^{2}$

Note: hypotenuse is always in front of right angle(the longest side)
