A 13-foot ladder is placed against a vertical wall of a building, with the bottom of the ladder standing on level ground 5 fee t from the base of the building. How high up the wall does the ladder reach?
1 answer:
The answer is 12 because (a^2 + b^2 = c^2)
5^2 + b^2 = 13^2
25 + b^2 = 169
169- 25 = 144
Sqaure root of 144 is 12 so If we plug that in..
25 + 144 = 169
5^2 + 12^2 =13^2
This all checks out

And what else is in the problem I do not get what the problem is
30% just means 30/100 which can be simplified to 3/10. In order to find the number of hits you just need to multiple .3 by the total attempts, being 240, which comes out as 76.
