Height of a Tower A water tower is located 325 ft from a building (see the figure). From a window in the building, an observer notes that the angle of elevation to the top of the tower is $39^{\circ}$ and that the angle of depression to the bottom of the tower is $25^{\circ} .$ How tall is the tower? How high is the window?

00:01 Okay, in this question, we are simply going to first draw the triangle that is shown in the diagram.
00:08 So we have the side, which is the water tower, which connects to the window on the building, which is going to be our vertex.
00:21 And then that creates a line, not down the middle, but it simply just divides it into two right triangles.
00:31 And then we have this one over here which is 39 degrees and then we have this one over here which is 25 degrees so now we're also given the distance between the bottom of the water tower to the bottom of the building which will then create which will then be 325 feet so now our job is to find the height of the tower.
01:09 So that will be over here.
01:11 We're going to solve from here to here, and that'll be...
01:16 Now, in order to solve it, we are first going to divide up other sides that we can look for...
