A man standing near a radio station antenna observes that the angle of elevation to the top of the antenna is

A = 62°. He then walks s = 110 feet further away and observes that the angle of elevation to the top of the antenna is B = 44° Find the height of the antenna to the nearest foot.

Trig HW help, I have a test tomorrow please explain and show steps!

1.) square root (3) sec theta = 2

2.) square root (3) sin theta +cos theta =1

I am confused on these problems, please help me understand how to do them. Thank you!

For the following, θ is a central angle in a circle of radius r. Find the length of arc s cut off by θ. (Round your answer to two decimal places.)

θ = 330°, r = 3 mm

If angle θ is in standard position and the terminal side of θ intersects the unit circle at the point (1/ sq root 17 ,−4/sqrt 17) find sin θ, cos θ,and tan θ.

I am confused as to how to work this problem out? I could not find a similar one in the textbook

How many grams of glucose should be weighed out to make 1 liter of a rehydration solution that contains 75 mmol of glucose (the molar mass of glucose is 180 g)?

You drive your car from salt lake city up into the mountains to go skiing. It is a nice fay in Salt Lake, with a temperature of 16 degrees C, and an atmospheric pressure of 0.85 atm. Up in the mountains it is freezing at -1.0 degrees c and atm pressure of 0.70 atm. If the volume of air in tires is 12L when you leave the city, what is it up in the mountains??

I wasn't sure what equation to use for this question. Thanks for your help
