Question

identify the correct angle for the given trigonometric value.
(your answer should be a letter)
$cos(square) = 0.5145$
hint: if you see one side labeled with $asqrt{x}$ for some numbers $a$ and $x$ that means you have $asqrt{x}$ on that side.

Explanation:

Step1: List triangle sides

Right triangle at W: $WX=5$, $WV=3$, $XV=\sqrt{34}$.

Step2: Calculate cos for angle X

For $\angle X$: adjacent=$WX=5$, hypotenuse=$XV=\sqrt{34}$.
$\cos(\angle X)=\frac{5}{\sqrt{34}}\approx0.8575$.

Step3: Calculate cos for angle V

For $\angle V$: adjacent=$WV=3$, hypotenuse=$XV=\sqrt{34}$.
$\cos(\angle V)=\frac{3}{\sqrt{34}}\approx0.5145$.

Answer:

V
