Question

if sin A
3/4


find cosa and ton A​

Answer 1

Answer:

cosa = √7/4

tana=3/√7 it is a correct answer

Answer 2

Answer:

hope it helps

Step-by-step explanation:

sin A = 3/4

P/H = 3/4

So, according to Pythagorean theorem

(Hypotenuse)^2 = p^2 + b^2

$4^{2} = 3^{2} + base^{2}$

16= 9 + base^2

16-9 = base^2

base = $\sqrt{7}$

COS A = Base/Hypotenuse

cos A = $\frac{\sqrt{7} }{4}$

tan A = Perpendicular Height/ Base

= $\frac{3}{\sqrt{7} }$
