Question

What is the value of $\cos 37$ in fraction?

Answer 1

Find the value of $\cos 37°$ in fraction.

In a triangle, a cosine function is one of the trigonometric functions that is equal to the ratio of the adjacent side and the hypotenuse i.e.$\cos \theta =\frac{\mathrm{base}}{\mathrm{height}}$

$\begin{array}{rcl}\cos 37°& \simeq & 0.8\\ & \Rightarrow & \cos 37°=\frac{8}{10}\\ & \Rightarrow & \cos 37°=\frac{4}{5}\end{array}$

Hence, the required value of $\cos 37°$ in fraction is $\frac{4}{5}$
