Question

9)
find the missing side. round to the nearest tenth.
16.1
16.0
16.2
16.3

Explanation:

Step1: Identify adjacent side and hypotenuse

Adjacent side to 68° is 15, hypotenuse is x.

Step2: Use cosine function

$\cos(68^\circ) = \frac{15}{x}$

Step3: Solve for x

$x = \frac{15}{\cos(68^\circ)}$

Step4: Calculate value

$\cos(68^\circ) \approx 0.3746$, so $x \approx \frac{15}{0.3746} \approx 16.1$

Answer:

16.1
