Sin theta = 24/25, cos theta > 0, Find cos(2theta)

Well... you don't necessarily need to get the cosine value, in order to get the double angle

$\bf \textit{Double Angle Identities}
\\ \quad \\
sin(2\theta)=2sin(\theta)cos(\theta)
\\ \quad \\\\
cos(2\theta)=
\begin{cases}
cos^2(\theta)-sin^2(\theta)\\
\boxed{1-2sin^2(\theta)}\\
2cos^2(\theta)-1
\end{cases}
\\ \quad \\\\
tan(2\theta)=\cfrac{2tan(\theta)}{1-tan^2(\theta)}\\\\
-------------------------------\\\\
cos(2\theta )=1-2sin^2(\theta )\qquad \qquad sin(\theta )=\cfrac{24}{25}
\\\\\\
cos(2\theta )=1-2\left( \cfrac{24}{25} \right)^2\implies cos(2\theta )=-0.8432$

Answer:

6:1:2.

Step-by-step explanation:

If Ben's score is x then Abel's is 6x and Cal's is 6/3 = 2x.

Then Abel's to Ben's to Cal's

= 6x : x : 2x

= 6:1:2.
