Using the technique in the model above , find the missing sides in this 30 -60 - 90 Short = 7 Long= Answer: Long leg = 7√3 units Step-by-step explanation: In a 30° - 60° - 90° special right triangle , the measure of the hypotenuse is twice the short leg, and the measure of long leg is the product of short leg and √3. As equation: Hypotenuse = 2(short) Long leg = (short)(√3) Short = hypotenuse/2 Short = Long/√3 or (long√3)/3 Given: Short = 7 units Find Long leg: Long leg = (short)(√3) Long leg = 7√3 units Find the hypotenuse: Hypotenuse = 2(short) Hypotenuse = 2(7) Hypotenuse = 14 units
