Question

If 15cotA =8 then the value of sinA will be

Answer 1

the answer is sinA=15

Answer 2

Answer:

Step-by-step explanation:

cotA =8/15,base/perpendicular

therefore by Pythagoras.

(base )2 + (perpendicular )2= hypotenuses

8*8+15*15=289

sq root of 289 is 17

and sinA = perpendicular/hypotenuses  

therefor sinA= 15/17
