Q1) I think the answer should be = 575*Cot(38.2) + 575*cot(27.4)
#1
A tunne must be constructed through a mountain. The angle of elevation from one side of the mountain is 38.2 . The angle of elevation fromthe other side of the mountain is 27.4 . The height of the mountain is 575m. What is the lenght of the tunnel through this mountain ?
Is the other end of the mountain the upper corner of a right triangle, or the lower ? ANd does anyone have the formula or a similar question I could copy the steps from ?
#2
A vertical light pole on a hillside casts a shadow of 55m long down the hill. If the angle of elevation of the sun is 48.3 and the angle of incilination of the hill is 21.4 . Find the height of the pole.
I know what the angle of elevasion and depression is, but what is the angle of incillination ? I dont get this question.
Fast answeres would be nice, its almost 3 am and i can barely force my yeyes to be open: Due date of this Assignment is tomorrow, its an online submission which has to happen before 11 am

[/I][/COLOR]575*Cot(38.2) + 575*cot(27.4) { here * represents multiplication not degree sign}
i.e. 575 X Cot(38.2degree) + 575 X cot(27.4degree)
or, 575 / tan(38.2degree) + 575 / tan(27.4degree)
