19. from two ships due east of a lighthouse and in line with its foot, the angles of
elevation of the top of the lighthouse are x and y, with x > y. the distance between the
ships is m. the distance from the lighthouse to the nearer ship is?

Step-by-step explanation:

tan x= AB/ BC+M

tan y=AB/ BC

tan y * BC = tan x*(BC +M)

tan y* BC /tan x=( BC +M)

tan y * BC - M* tan x/ tan x= BC

a. (14,375+570)(5.3) b. 158,417$

step-by-step explanation:

a. you are basically just setting up the equation. f= amount of debt hence 14,375. g= how much she is borrowing from her parents weekly hence 570 and t= the interest on her debt. creating the equation.

b.   14,375+570= 14,945

      14,945 x 5.3 = 79,208.5

      79,208.5 x 2(years) = 158,417(answer)

yes they are the same
