Aladder leans against a building. the angle of elevation of the ladder is 70°. the top of the ladder is 25 ft from the ground. to the nearest tenth of a foot, how long is the ladder?

Sine rule

a/Sin(A) = b/Sin(B) = c/Sin(C)
     b
 C / |
a / _| A 
    B  c

We know that a = 70 degrees and A = 25 foot
So 70/Sin(25) = Something
We also know we want C, and that c = 90 degrees
So 70/Sin(25) = 90/Sin(C)
Then you have to rearrange the equations. Start with Multiply all by Sin(C)
So [Sin(C)][70/Sin(25)] = 90
Then divide everything by 70/Sin(25)
So Sin(C) = 90/[70/Sin(25)]
Now you want to isolate C, so Sin-1 everthing
So C = Sin-1{90/[70/Sin(25)]}
So C = 32.91309534
To the nearest tenth, 32.9ft
Hope that helps :)

32.9 ft 
That's the answer!
Hope it helps! 

29. because you will divide each number of months by 12 to find the number of years. which would mean, 5, 12.5, 16, 45, 50, 72.5. which is crazy. anyhow, i think you find the median in the middle. and yea hope your test goes good

The answer is -pie over 2
