The angle of depression of a point P on the ground from the top T of a building is 23.6. If the distance from P to the foot of the building is 5 cm. Calculate the height of the building, correct to the nearest degree. ​

We got a problem here.  What is the unit of measure for 23.6 and are you sure the 5 cm should be 5 m?

Step-by-step explanation:

add an !

step-by-step explanation:

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
