Question

What is the measure of angle BAC? Round to the nearest

whole degree.
A. 0°
B. 1°
C. 44°
D. 48°

Answer 1

the answer is c. 44, i hope it works

Explanation:

Answer 2

`44^(\circ)`

Explanation:

We are given that

`sin^(-1)((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)((3.1)/(4.5))=x`

`sinx=(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)`
