Question

A 30-60-90 triangle has a hypotenuse of 10. Use special right triangle formulas to find the long side.

Answer 1

From special right triangle formulas I know the ratios of the sides.
1,2,sqrt(3)
where 2 is the hypotenuse

and the long side is sqrt(3)
so the long side is 10/2*sqrt(3)=5sqrt(3)
all done
PS short side is 5

Answer 2

DLS is not correct

Answer 3

why?

Answer 4

a 3,4,5 triangle is a perfect triangle for the Pythagorean theorem but not necessarily at 30,60,90 degrees.

Answer 5

If you look at the unit circle...
