Radio tower is located 250 feet from a building. From a window in the building, a person determines that the angle of elevation to the top of the tower is 27∘ and that the angle of depression to the bottom of the tower is 20∘
How tall is the tower?

-60.75

step-by-step explanation:

just add the numbers then put the negative sign on it

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9

doubled
