Question

If 3 tanA=4 then find sin A and cosA ?

Answer 1

Answer:

SIN A =3/5

COS A=4/5

Step-by-step explanation:

3TAN A=4

TAN A=4/5

4/5= OPPOSITE SIDE /ADJACENT SIDE

SIN A = O/HYPOTENUSE

COS A = A/HYPOTENUSE

HYPOTENUSE* = OPP*+ADJ

HYP*=3*+4*

= 9+16

= 25

HYP*= 25

HYP=

$\sqrt{25}$

HYP=5

THERE FORE,

SIN A = O/H

= 3/5

COS A = A /H

= 4/5

HERE * = 2
