Answer:

b. 75°

Step-by-step explanation:

Draw a triangle. Write a person name and a point name (a letter) at each vertex: Sam A, Sonny B, and Sal C at the vertices.

Write the distances as AB = c = 153 ft; AC = b = 201 ft; BC = a = 175 ft.

We are looking for angle B.

Since we have a triangle with three side lengths and no angle measures, we use the Law of Cosines.

b^2 = a^2 + c^2 - 2ac \cos B

201^2 = 175^2 + 153^2 - 2(175)(153) \cos B

40401 = 30635 + 23409 - 53550 \cos B

-53550 \cos B = -13643

\cos B = \dfrac{-13643}{-53550}

\cos B = 0.254771242

B = \cos^{-1} 0.254771242

B = 75^\circ

Answer: b. 75°

Inga [223]

Answer:

The answer to your question is 10 dm

Step-by-step explanation:

Data

length of a rectangle = x + 4

height of a rectangle = x - 6

Area of the rectangle = 56 dm²

length of the square = x

Process

1.- Find x with the information given for the rectangle

    Area = length x height

Substitution

    56 = (x + 4)(x - 6)

Expand

    56 = x² - 2x - 24

Equal to zero

            x² - 2x - 24 - 56 = 0

Simplify

             x² - 2x - 80 = 0

Factor

            (x - 10)(x + 8) = 0

Equal to zero

             x₁ -10 = 0          x₂ + 8 = 0

             x₁ = 10               x₂ = -8

2.- Conclusion

The length of the square is 10 dm because there are no negative lengths.

2.5x + 6 = 3.25x + 3

2.5x = 3.25x - 3

-0.75x = -3

x = 4 cookies
