Answer:

The answer is (a) ⇒ tanx = sinx/cosx

Step-by-step explanation:

∵ (sinx)(cosx)(tanx) = (sinx)(cosx)(sinx/cosx) = sin²x

∵ sin²x = 1-cos²x

∴ L.H.S = R.H.S

∴ (sinx)(cosx)(tanx) = 1 - cos²x

Step-by-step explanation:

All triangles equal 180 degrees to this is what I did:

8x + 2 + 70 + 60 = 180

8x + 2 + 130 = 180

8x + 132 = 180

subtract 132 from each side

8x = 48

now divide each side by 8 to isolate the x

x = 6.

Answer:

I think that the answer would be C because you have to multiply the term at the top. This would mean you would not do C. Sorry if this is wrong. At least you have your eliminating process now. lol so doing C is out of the box, which makes C your answer.
