D. 48°

Answer 1

Answer:

the answer is c. 44, i hope it works

Step-by-step explanation:

Answer 2

Answer:

$44^{\circ}$

Step-by-step explanation:

We are given that

$sin^{-1}(\frac{3.1}{4.5})$

We have to find the measure of angle BAC.

To find the measure of angle BAC we will use the value of sin inverse function from sin inverse table.

Angle BAC=x

$sin^{-1}(\frac{3.1}{4.5})=x$

$sinx=\frac{3.1}{4.5}$

$sinx=0.688$

$x=sin^{-1}(0.688)$

Substitute $sin^{-1}(0.688)=43.5$

$x=43.5^{\circ}$

$x=43.5\approx 44^{\circ}$

Hence, the measure of angle BAC=$44^{\circ}$
