The formula of a slope:

We have the points (-4, -3) and (-3, s) and the slope m = 3. Substitute:
Answer and Step-by-step explanation:
90ft = a
55ft = b
50ft = c
Plug into equation.

29.4° is the answer.
The area of a triangle is A= 1/2bh. Plugging in the values you know, 30= 1/2*12*h.
Solving for h,
30= 1/2*12*h
30= 6h
h=5
The height of the triangle is 5 units.
