In a 30-60-90 triangle, what are the ratios of the sides to one another?
I'm doing a study guide and one question that has had me stumped is this: you have to find the perimeter of a right triangle with a hypotenuse of 10 square root of 3 and a measurement of 30. I know I'm supposed to follow the 30 60 90 format, but.....
The hypotenuse is opposite the 90° angle and is given as .
The 30° angle is opposite the shorter leg, and the 60° angle is opposite the longer leg. Since you state you are supposed to use the 30-60-90 format, I took that to mean you have been given the ratios of the sides to one another in such a triangle. If not, we can use some basic trigonometry to get these ratios:
Let a be the shorter leg, b be the longer leg, and c the hypotenuse. Using the definition:
on the 3 angles, what do you find?
