Didn't do the trig on it, but just thinking logically, I'd say E.

7 squared plus unknown = 25 squared 

unknown = 24
24 - 4 = 20
20 squared + uknown squared = 25 squared
 
unknown = 15
15-7 = 8
 
E

I did the math. It is E.

A squared plus B squared equals C squared.
7 squared plus B squared = 25 squared.
49 + B squared = 625
B squared = 576
B = 24

Then

A squared + 20 squared = 25 squared
A squared + 400 = 625
A squared = 225
A = 15

Then

15 - 7 = 8

I did the same thing basically as SVT and tried to keep it challenging by doing it in my head. The square root of 576 I had to think on for a moment or two...glad it was a whole number!

Intuitively, you'd think a triangle with a hypotenuse of 25 and a base of 7 would have a shorter opposite side. Now, can everybody sing "On top of Catheti"?

But how long will it take the guy to hit the ground once the top slides down and the base of the ladder kicks out?

A rope ladder on a boat hangs over the side of the boat and just reaches the water. Its rungs are 8 inches apart.

How many rungs will be under the water when the tide rises 4 feet?

None. The boat floats up and remains the same height on the water.

E.  is the correct answer...

This one will require a bit more thought...  It's not hard, it's just not obvious...

Going to start you off on a savings plan.
 
Picture a 31 day calendar month.  On day 1, I'll give you 1 cent.  All I want you to do is double the amount each day until the end of the month.  You may want a calculator or Excel to help you, but it's more fun guessing first how much you think you'll have at the end.
