3. a. What is m<Y to the nearest degree?
b. Reasoning Suppose you know the lengths
of all three sides of a right triangle. Does it
matter which trigonometric ratio you use to
find the measure of any of the three angles? Explain.

@ phi it says to the nearest degree = rounding so \[\approx68\]

so for part b i think that it does matter which function you use, but im not entirely sure why

phi Group TitleBest ResponseYou've already chosen the best response.1
it should not matter, unless two of the legs are given with more precision than the 3rd side.

highschoolmom2010 Group TitleBest ResponseYou've already chosen the best response.0
what do you mean with more precision than the third
 11 months ago

phi Group TitleBest ResponseYou've already chosen the best response.1
if one side was sqrt(3), but they round it to 1.7, that would not be the best leg to use.... but I think you can use any of the trig functions if you know all 3 sides

Part (b) is a strange question Does it matter which trigonometric ratio you use to find the measure of any of the three angles? one of the 3 angles is a 90 degree angle, and you would not use trig to find it.
