Question

What’s the correct answer for this?

Answer 1

A. sin x = 6/10 and cos x = 8/10.

Explanation:

If tan x is 6/8 the opposite side to x = 6 and the adjacent side = 8.

So the hypotenuse of the triangle = √(6^2 + 8^2)

= √100

= 10.

So sin x = 6/10 and cos x = 8/10.

Answer 2

A

Explanation:

Suppose p = 6 and b = 8, so that tan x is 6/8

Then the hypotenuse is sq rt (6x6 + 8x8) = sq rt (36 + 64) = sq rt (100) = 10

So sin x = p / h = 6 / 10

And cos x = b / h = 8 / 10

So A is the answer
