I have a right triangle, but i only have the measures for its angles (90,60,30) Is there any way for me to find the length of one side

A circle has a radius of 19m . Find the radian measure of the central angle θ that intercepts an arc of length 5m . Do not round any intermediate computations,...

plz help by giving solution

i know that the answer is 1/4 but i dont know how they solved it

ABC is a triangle. D is the center of BC . AC is perpendicular to AD. prove that cos(A)⋅cos(C)=2(c^2−a^2)/3ac

sin(x) + sin(3x) = 4 sin(x) cos^2(x)

A) sin(2x) B)cos(2x) c) tan(2x)

Let , (2,-3) be a point on the terminal side of θ . Find the exact values of sinθ , secθ , and tanθ .

Find the area of triangle ABC to the nearest tenth if AB = 14 ft, BC = 10 ft, and ∠ABC = 74°.

This is for my trig class, thanks for the help! If you could, could you please show all your work? Thanks again!

what is Tan(a)

Trigonometry question

If sin(x) = 1/4 and x is in quadrantI,find the exact values of the expressions without solving for x. (a) sin(2x) (b) cos(2x) (c) tan(2x)

16 cos(2θ) = 16 cos^2(θ) − 9

Please solve..
