A building casts a 16 ft shadow. A six foot man standing next to the building casts a 2.5 ft shadow. How tall is the building? (show your work)

the building is 38.4 feet tall

Step-by-step explanation:

because the ratio for the man is 6:2.5 and the building is x:16

so x = 38.4

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
