An aerial photographer who photographs real estate properties has determined that the best photo is taken at a height of approximately 483 ft and a distance of 858 ft from the building. What is the angle of depression from the plane to the building?

x = distance from the building = 837ft

y = height = -483ft (The building is DOWN from the plane.)

θ = angle of depression = to be determined

tan θ = y/x

tan θ = -0.577060932

θ = arctan (-0.577060932)

θ = -29.98756509° ≈ -30° (The building is DOWN from the plane.)

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
