Question

sin a = 3/4 , calculate cos A and tan A​

Answer 1

Answer:

the value of cosA is 5/4 and the value of tan A is 3/5

Answer 2

Answer:

sin A = 3/4

p/h = 3/4

3= perpendicular

4= hypotenuse

base² = h² - p²

b² = 4²-3²

b²= 16-9

b²= 7

b=

$\sqrt{7}$

cos A = b/h

= under root 7 / 4

Tan A = p/b

= 3/under root 7
