**Henry**, Saturday, July 13, 2013 at 8:30pmDraw a picture of the situation:

1.Draw ver. line AC with A on the bottom.

2. Add point D on line AC.

3. Draw a hor. line from A to the left.

Label it AB. Now we have a rt angle.

4. Draw hyp. BC.

5. Draw hyp. BD.

<ABC = <ABD + <DBC = 61.5o

56.33 + <DBC = 61.5

<DBC = 5.17o

<ACB = 180-(61.5+90) = 28.5o

<BDC = 180-(28.5+5.17) = 146.33o

sin5.17/25 = sin146.33/BC

BC = 153.8 Ft.

sin61.5 = (25+h)/153.8

h = 110 Ft. = Ht. of Bldg.
