The front of a tent is in the shape of an equilateral triangle with side lengths of 8 feet. A tent pole is placed from the peak of the tent to the center of the opposite
side (floor of the tent). To the nearest tenth of a foot, what is the approximate
height of the pole?

step-by-step explanation

2r= 2300

r =1150

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
