Question

Tan A= 5/12 ho To cos A ka kitne me hoga

Answer 1

Step-by-step explanation:

tan A=5/12

then opposie =5

and base =12

By using Pythagoras theorem

(hypotenuse)²= (base)²+(opposite)²

putting values we get,

(h)²=(12)²+(5)²

h=√144+25

h=√169

hence h=13

then cos A= base/hypotenuse

so cosA=12/13
