Best ResponseYou've already chosen the best response.1dw:1443954591287:dw So we're starting off at \(P (1,0)\) and we're looking for \(\mathbf {\overline t}\)

Best ResponseYou've already chosen the best response.1To do that, we're simply going to subtract the distance, \(\mathbf t = 3.5\) by \(2\pi\) to find \(\mathbf{\overline t}\)

Best ResponseYou've already chosen the best response.1\[\overline t = 2\pi  3.5 =~?\] This is what you call the reference number.

Best ResponseYou've already chosen the best response.1Yeah but I wouldn't limit it to 3.14 unless specifically asked for, it gives an inaccurate reading and the reference number is simply an approximation.

Best ResponseYou've already chosen the best response.1so \(\overline t \approx 2.78\)

Best ResponseYou've already chosen the best response.0thank you so much! You literally saved me. I have a quick question about trigonometry and right angles. I know all the angles but don't know any of the sides

Best ResponseYou've already chosen the best response.1Youre not really giving me any answer choices to work with so I can check whether my solution matches up to any of the choices.

Best ResponseYou've already chosen the best response.0oh there are no answer choices. I'm taking an online program called wamap. I just have to input my answer and see if it's right or not

Best ResponseYou've already chosen the best response.0I actually own that book :) and it doesn't really mention anything about finding unknown sides
