Answer:
The height of the building is approximately <u>73 m</u>.
Step-by-step explanation:
The triangle EFG is shown below.
Given:
Length of shadow of building is,
Angle of inclination of Sun with the vertical is 25°.
Therefore, the angle of inclination of Sun with the horizontal is given as:
Now, in triangle EFG as shown below, we use the tangent ratio to determine the height of building EF. Therefore,
Therefore, the height of the building is approximately 73 m.

H^2=13^2-5^2
h^2=169-25
h^2=144
h=V144
h=12
A=b*h/2=10*h/2
A=10*12/2=120/2=60 cm^2
Answer:
The third choice is the one you want
Step-by-step explanation:
The solutions are found where the graphs intersect each other, which is in 3 places. We are only worried about the x values here. It appears that they cross, on the far left, at x = -2, in the middle at x = .5, and on the far right at x = 3.5
