Mekhanik [1.2K]
So, 75% is the same as 3/4 right? The best way to do this would be to first find 1/4.

240/4 = 60

Now you know that 1/4 equals 60.

but.... you have 3/4 

60 x 3 = 180

180 kids voted for James.

Suppose sin(A)=-0.78. use the trig identity sin^2(A)+cos^2(A)=1 and the trig identity tan(A) = sin(A)/cos(A) to find tan(A) in q
Paladinen [302]

In quadrant IV, \cos(A) is positive. So

\sin^2(A) + \cos^2(A) = 1 \implies \cos(A) = \sqrt{1-\sin^2(A)} \approx 0.6258

Then by the definition of tangent,

\tan(A) = \dfrac{\sin(A)}{\cos(A)} \approx \dfrac{-0.78}{0.6258} \approx \boxed{-1.2465}
