Question

question 17 5 pts find the missing side. round to the nearest tenth. x 16 63° x=

Explanation:

Step1: Identify trigonometric ratio

We know $\cos\theta=\frac{\text{adjacent}}{\text{hypotenuse}}$. Here $\theta = 63^{\circ}$, adjacent side is 16 and hypotenuse is $x$. So $\cos63^{\circ}=\frac{16}{x}$.

Step2: Solve for $x$

We know $\cos63^{\circ}\approx0.454$. Then $x=\frac{16}{\cos63^{\circ}}=\frac{16}{0.454}\approx17.9$.

Answer:

$x\approx17.9$
