Question

Given 17cosA = 8, then calculate SinA and TanA.

[Hint: CosA means angle at vertex A]

Answer 1

Answer:

15/17, 15/8

Step-by-step explanation:

17cosA = 8

cosA = (8/17)

Now,

sin^2A = 1 - cos^2A

           = 1 - (8/17)^2

           = 225/289

           = (15/17)^2

SinA = 15/17.

Now,

TanA = (sinA/cosA)

         = (15/17) * (17/8)

         = 15/8

Hence, sinA = 15/17, TanA = 15/8

Hope it helps you.
