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,...

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

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

16 cos(2θ) = 16 cos^2(θ) − 9

tan(x) − 2 sin(x) tan(x) = 0

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

If sin(x) = 1/8 and x is in quadrant I, find the exact values of the expressions without solving for x. a) sin(2x) b) cos(2x) c) tan(2x)

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

cos (sin-1 5/13) answer in simplified fraction or integer

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

Please solve..

plz help by giving solution

Trigonometry question

Simplift the expresslion by using angle formula
