Cosine

Calculate the cosine of the smallest internal angle in a right-angled triangle with cathetus 3 and 8 and with the hypotenuse 8.544.

Correct answer:

cos θ =  0.94

Step-by-step explanation:

$$\begin{gathered} \cos \theta =\max (3,8)\mathrm{/}8.544 \\ \cos \theta =8\mathrm{/}8.544=0.94 \end{gathered}$$
