Question

In a triangle ABC right angled at A, having AB - 5cm, and
BC = 12 cm, find sin B, cos C and tan B
​

Answer 1

Step-by-step explanation:

AB= 5cm, BC = 12cm, AC =?

so by using pythagoras theorem,

AC = _/(12)2 - (5)2 = _/144 - 25 = _/119

sin B = AC/BC = _/119 / 12

cos C = AC/BC = _/119 /12

tan B = AC/AB = _/119 /5
