Answer:

131.41 degrees

Step-by-step explanation:

Given the equation

5(sinθ+3) = sinθ+12

5sinθ+15 = sinθ+12

5sinθ-sinθ = 12 - 15

4sinθ = -3

sinθ = -3/4

θ = arcsin(-0.75)

θ = -48.59 degrees

Since sin is negative in the 3rd quadrant

α = 180 + θ

α = 180 - 48.59

α = 131.41degrees

Hence the required angle is 131.41 degrees

The question is below thanks
iren [92.7K]

Answer:

10.02 units

Step-by-step explanation:

FH = \frac{82}{360} \times 2 \pi r (Multiplying the circumference of the circle by the arc's degree over the total degree of the circle will find the length of the arc FH)

FH = \frac{82}{360}\times 2 \pi (7)

=\frac{82}{360}\times14\pi

=\frac{287\pi}{90}

=10.02 (to the nearest hundredth)

∴ The length of the arc FH is 10.02 units to the nearest hundredth.

Hope this helps :)
