What basic trigonometric identity would you use to verify that sin x con x tan x= 1-cos^2x?

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

so what is the problem what are they asking you to solve

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
