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}

Answer:

B.) -7/1

Step-by-step explanation:

Finding the slope we use: y2 - y1/x2 - x1

m = -1 - 6/-3 - (-4)
