Okay i'm doing h.w. right now and i'm trying to solve these without having to look at my notes:
The angle elevation of the sun is 40 degrees. To the neaest foot, find the height of a tree whose shadow is 35 ft long.
35 x tan (40) = 29 degrees
A washington monument is 555 ft high If you are standing one quarter of a mile or 1320 ft, from the base of the monument, and looking to the top, find he angle of elevation to the nearest degree.
-1 tan (555/1320) = 2 degrees
A road is inclined at an angle of 5 degrees. After driving 5000 ft along this road, find the driver's increase in altitude. Round to the neares foot.
This one and the next one, i'm a bit lost at going about solving. Would I use sin for this?
A telephone pole is 55 ft tall. A guy wire 88 ft long is placed from the ground to the top of the pole. Find the distance between the wire and the pole to the nearest degree.
I must have misread my calculator when i punched it in, I had those exact steps written out.
For the third one, i've done this, not sure if its right though:
5000 x tan(5) = 437.4
a + 437.4 = 5000
On a side note, how did you get that problem to show up like that?
