Best Answer

About 8.5 (8.4868). The other leg is about 5 (4.9).

Since the shortest leg is opposite the smallest angle, 30 degrees, the longest leg length equals to 8.49 units

(9.8 x sin 60 degrees = 9.8 x 0.866).

(5 x sin 30 degrees = 9.8 x 0.5)

The lengths of the legs (rounded) are:

- 5
- 8.5

The legs of a right triangle have the same length and the hypotenuse is 30 ft, each leg would be of length 21.21 ft.

The length of the hypotenuse of a right triangle with legs of lengths 6 and 8 inches is: 10 inches.

The lengths of the legs of a right triangle are 15 cm and 20 cm. What is the length of the hypotenuse?

If the hypotenuse is the square root of three, then the legs are (root 6)/2. If the hypotenuse is 12, then the legs are 6(root 2). This is because, for any given right isosceles triangle, the length of the hypotenuse x is root two times the length of the legs.

The hypotenuse of the right angle triangle is 89 units in length
