All right, as we look at this question, it says a ladder leans against the side of a house.
00:05
So let's say we have our house here, all right? we have a ladder leaning against the side of the house.
00:11
Notice we have a right triangle here, the bottom of the ladder.
00:17
It's from the side of the house.
00:18
How high is the top of the ladder from the ground? all right? looking at this picture, we are missing some sort of information.
00:28
So let's say we have an 18 foot ladder, all right? additionally, besides that information, we might have that 18 foot ladder.
00:38
And let's say the angle of elevation to the top is say 80 degrees.
00:45
Once we have that information, we can go ahead and solve.
00:48
So we know the height is our opposite side...
