Write an expression for tan x degrees and an expression for tan(90-x)degrees, in terms of a, b, and c. How is the tangent of an angle related to the tangent of the angle's complement?
Write and expression for (sin X degrees)squared + (cos x degrees) squared in terms of a, b, and c. Then use the Pythagorean Theorem to simplify your expression
A) Use triangel ACD to write expressions for p squared + q squared in terms of b and for p in terms of b and angle A.
B) Find a squared in terms of c, p and q. Give your answer in expanded form.
C) Use results from parts a and b to find an expression for a squared in terms of b, c and angle A
D) Use the results from part c to find the angle A round your final answer to the nearest tenth. (with this problem is triangle ABC with side lengths AB = 27 AC=32 BC= 23)
other problem:
when the sun is shining at a 62 degree angle of depression, a flagpole forms a shadow of length x feet. Later the sun shines at an angle of 40 degrees, and the shadow is 25 feet longer than before
a) Draw a picture of the scenario
B) write two expressions for the height of the flagpole in terms of x
C) how tall is the flagpole to the nearest tenth of a foot
Thanks a please show all work.
