1)Given triangle ABC with a=12,b=10 and c=8, find the angles in degrees and minutes.?

2)Find the area of triangle AC if a=40ft,b=25ft, and %26lt;c=30 degrees.





3)A triangle has sides 18,27, and 36. What is its area?





4)If an observer is 200 feet from a building and the angle of elevation to the top of a building is 60 degrees, what is the height of the building?





5)(a) Express 32 degrees30' in decimal degrees.


(b) Express 25.15 in degrees and minutes.





6)a. If you are given two sides of a triangle and the included angle, how would you find the third side?


b. If you know the three sides of a triangle, how can you find it's area?





7)show that sin thea =cos thea tan thea





true or false


8)sin thea = cos(90- thea)





9)tan thea= -cot(90- thea)





10) sin thea = 1/ csc thea, where sin thea is not equal to 0





11)cos thea= 1/sec thea, where cos is not equal to 0

1)Given triangle ABC with a=12,b=10 and c=8, find the angles in degrees and minutes.?
ever heard of a^2 = b^2 + c^2 -2bc Cos(a)?





or a/Sin(a) = b/Sin(b) = c/Sin(c)
