Question 1025202: How do I go about sovling these triqonometry because I am lost here. Please show yours in how you slove these. Thank you for your help and time.
looking at an image, one angle is angle x, and another is the right angle (90o). Since the angles in a triangle add up to 180o, the other angle will be 90 - x. For the unlabeled angle above, the angle 90 - x: hypotenuse is 5, opposite is 4, and the adjacent is 3.
7. what is the sin of Sin(90 – x)?
8. What is the cos?
9. What is the tan?
10. What is the sec?
11. What is the csc?
12. What is the cot?
13. What is the hieght of a building 5 degree, Angle 1 degree,and a Distance of 500 meters?
Answer by richard1234(7193)   (Show Source):
You can put this solution on YOUR website! Is the opposite side to the (90-x) degree angle 4 (and adjacent side 3?)?
If so, sin(90-x) = opposite/hypotenuse = 3/5 (where "opposite" refers to the side opposite the angle with measure 90-x deg)
cos(90-x) = adjacent/hypotenuse = 4/5
tan(90-x) = opposite/adjacent = 4/3
However, I cannot answer the last two (cos(90-x) and tan(90-x)) because you did not specify whether you meant cos(90-x) or cos x (trig functions require an argument!).
For the next three, use the definitions sec x = 1/cos x, csc x = 1/sin x, cot x = 1/tan x.
