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

Answer:

6

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.
