# Given calculate all other trigonometric ratios.

Given:

We know that,

Let,

BC = 12k and AC = 13k

where, k is any positive integer.

In right angled ∆ABC, we have

(AB)2 + (BC)2 = (AC)2 [by using Pythagoras theorem]

(AB)2 + (12k)2 = (13k )2

(AB)2 + 144k2 = 169k2

(AB)2 = 169k2 – 144k2

(AB)2 = 25k2

AB = 25k2

AB =±5k [taking positive square root since, side cannot be negative]

Now, we have to find the value of other trigonometric ratios.

We, know that
