A 30- 60- 90 triangle has a hypotenuse of length 9.8 What is the length of the longer of the two legs?

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 lengths of the legs of a right triangle are 15 cm and 20 cm. What is the length of the hypotenuse?
In an isosceles right triangle the hypotenuse is radical three and if the hypotenuse is 12 then what is the smaller leg of that triangle?
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.
