+4624 What is the sum of the lengths, in centimeters, of the two legs of a 30-60-90 right triangle, if the length of the hypotenuse is 2√6 centimeters?
+118703 Draw an equilateral triangle of side length 2
now split it down the middle to form two congruent right angled triangles.
The angles on these 2 triangles are 90,60, and 30 degrees
the side lengths are 2,1 and sqrt3 (gained using Pythagoras's theorum)
The the hypotenuse of a similar triangle is 2root6 then that is a dilation of root6
2*sqrt6 = 2sqrt6
1*sqrt6 = sqrt6
sqrt3*sqrt6 = sqrt18 = 3sqrt2
Perimeter is
2√6+√6+3√2=3√6+3√2cm
