So we have a transit that is 200 feet from the base of a building.
00:07
There's a man on top of the building.
00:13
The angle of elevation from the top and the bottom of the man are 45 and 44 degrees.
00:20
So to the top of the man, 45, to the bottom of the man, 44.
00:29
And we want the man's height.
00:32
Okay, so what we've got are two right triangles.
00:38
First one, i'm going to draw, uses that 45 degree angle.
00:46
And this is going to be x, and x is going to be the top of the man to the ground.
00:58
Then i'm going to have a second triangle, clearly not to scale, with a 44 degree angle...
