R(s + t) = st

Rs + Rt = st

Rs - st = -Rt

s ( R - t) = -Rt

*s = - Rt / (R - t) Multiply through by -1 on the right.

*s = Rt / (t - R) Put in the brackets in your answer. What you have been writing means

s = Rt/r - R you need the brackets. The stars mean that either could be an answer. I think your problem could be the brackets. Now I'm reasonably certain this is correct.

Find the side length x. Round your answer to the nearest hundredth.

Side length-80

So we know that for a Right Angle, both sides have to measure up to 90 degrees. If one side is 10, and both sides need to add up to 90, then we can take 10 away from 90. That would be 80. 80 + 10 = 90. So the missing side length is 80.

Answer:

12.5 pi or 39.26990

Step-by-step explanation:

First we can find the radius, which is half the diameter, 5 feet. To find the area of a semi-circle we would find the area of the circle and then divide by 2:

$\frac{\pi r^2}{2}$

We can substitute what we have:

$\frac{25\pi }{2}$

This gives us:

12.5 pi or 39.26990(Not sure what format you need it in)
