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 26 centimeters?

The  length of the leg opposite the 30°  angle = (1/2) (hypotenuse)  = (1/2)(26)  = 13

 

The length of the  side opposite the  60° angle =   (side opp 30° angle)  * sqrt (3)  = 13sqrt (3)

 

Sum of sides =   26 + 13 + 13sqrt(3)   =   [39 + 13sqrt (3) ] cm ≈ 61.5 cm
