solve for $x$. round to the nearest tenth of a degree, if necessary.\nanswer attempt 1 out of 2\n$x =$ $square$ °
Answer
Explanation:
Step1: Identify adjacent, hypotenuse
For $\angle x$, adjacent side $=7.2$, hypotenuse $=12$.
Step2: Apply cosine definition
$\cos(x) = \frac{\text{adjacent}}{\text{hypotenuse}} = \frac{7.2}{12}$
Step3: Calculate inverse cosine
$x = \cos^{-1}\left(\frac{7.2}{12}\right)$
Step4: Compute and round value
$x = \cos^{-1}(0.6) \approx 53.1^\circ$
Answer:
$53.1$
