Question

the measure of angle bac can be calculated using the equation sin⁻¹(3.1/4.5)=x. what is the measure of angle bac? round to the nearest whole degree.

Explanation:

Step1: Calculate the ratio

$\frac{3.1}{4.5} \approx 0.6889$

Step2: Compute inverse sine

$\sin^{-1}(0.6889) \approx 43.6^\circ$

Step3: Round to nearest degree

$43.6^\circ \approx 44^\circ$

Answer:

C. 44°
