Suppose Theodore is laying on the ground looking up at the sun that appears just over the top of a tree at an angle of elevation of 27º. He
is located 32 feet away from the base of the tree. How tall is the tree? Round to the nearest tenth of a foot.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

i think the amount would be $140.62
