IgorC [24]

Answer:

5 ft/s

Step-by-step explanation:

Let L be the length of the ladder. The relation between the angle and distance X is:

X = L * sin θ the change of X will be:

dX/dt = L * cos θ If we evaluate the expression when θ = π/3, we get the change of X:

dX/dt = 10 * cos(π/3)

dX/dt = 5 ft/s

Helpppp please please THIS IS TIMED NO LINKS or I will report YOUU I WILL MARK BRAINLIEST Please give me an explanation

Answer:

14800

Step-by-step explanation:

Area of trapezoid = $A=\frac{a+b}{2}h$

Using the formula above, our equation will look like this:

$\frac{145 + 225}{2} * 80 = 14800$

145 + 225 = 370

370/2 = 185

185 * 80 = 14800
