Express in decimal form to one place

Find the length of the arc s in the figure. (Assume r = 5 and θ = 128°.) I have been working at this problem for an hour now! I do not understand this problem. The crazy thing is that I...

a resistor and an inductor are in series , if R=770Ω and Xc=1100Ω. find tan θ and θ in degrees.

given cosθ=9/13 and sin θ negative, find θ in degrees between 0 and 360 degrees.

Use power-reducing identities to write the given trigonometric expression in terms of first power of cosine function. answer: sin4x cos2x=____ /____(1-cos2x-___+cos2x___) "___"...

Here's the exact formatting, If cos(t)=−7/9cos(t), where π<t<3π2π<t<3π2, find the value of the following trigonometric function cos(2t)

box is 500N

I would like to know the tangent for 84 degrees.

Compound angles and exact values meed to he used

Please tell me I know sin2A, how to find Sin^2A, I don't know cosA or A?

This is all the information I got.. I can answer questions you have on the problem.

Looks like this kinda |\ | \ |__\ |__|_\

If 0 ≤ θ <2π, for what angles, θ, if any, is tan θ undefined?

Trigonometry

If you are given 3 sides of a triangle, explain how you would find all three angles?

Kevin is riding a mini Ferris wheel. He reaches the maximum height of 9m at 5s and then reaches the minimum height of 1m at 65s. a.What is the period (the length of time to complete one cycle)...

cant figure this out

If x is greater than or equal to 0 but less than pi and cos(x)=k, express tan^2(x/4) in terms of k

This is translated from a trigonometry problem in another language, I hope you understand it.

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
