Question

tan A=4/3 हो, तो 1 - cos A का मान होगा
​

Answer 1

tan A=4/3=p/b

p=4 b=3

h=5

cosA=b/h=3/5

1-cosA=1-3/5= (5-3)/5 =2/5

Answer 2

Answer:

2/5

Step-by-step explanation:

tanA = 4/3 = perpendicular/base

Perpendicular= 4

base = 3

By Pythagoras theorem

H² = P²+B²

H²=(4)² +(3)²

H²= 16+9

H=√25

H= 5

cos A= Base/ Hypothenus

CosA= ⅗

* 1- cosA

= 1-3/5

5/5-3/5

= 2/5

This is the solution
