How do you find the sides of a 30 60 and 90 degree triangle when the hypotenuse is 9.8?

You can use 2 methods:
1. Use Pythagoras:
For a 30/60/90 triangle the short side is half of the hypotenuse = 4.9
Then 9.82 - 4.92 = (third side)2 = 8.487
or
2. Use trigs:
Sin 30o x 9.8 = opposite side = 4.9
Cos 30o x 9.8 = adjacent side = 8.487

How do you find the other 2 sides of the triangle if you know the hypotenuse?
You need more information unless it's a right triangle and a common pathagorean triangle, such as a 90 degree angle with a hypotenuse of 5 would have legs of 3 and 4.
How do you find the two shorter sides of a triangle when all you know if the hypotenuse and nothing else?
If it has an hypotenuse then it is a right angle triangle and if you know its angles then use trigonometry to find its other two sides.
How do you find degree of hypotenuse on a right angle triangle?
By using trigonometry
How do you find one of the shorter sides of a right angled triangle knowing the hypotenuse and one of the shorter sides?
a^2 + b^2 = c^2 c= hypotenuse a and b are the legs (sides) of the triangle
What is the formula to find the hypotenuse of a triangle with two sides?
Providing that it is a right angle triangle then use Pythagoras; theorem:- a2+b2 = c2 where a and b are the lengths of the sides and c is the hypotenuse

Can you find the length of the sides of a right triangle knowing only the hypotenuse?
No.

How do you find the hypotenuse of a non right triangle?
By definition, the hypotenuse is the side opposite the right angle in a right angled triangle. Therefore, a hypotenuse does not exist as one of the three sides in a non-right angled triangle.
How do you find the angle of a an right triangle?
The 90 degree angle in a right angle triangle is opposite its hypotenuse.
What is the length of a hypotenuse?
A hypotenuse is the longest side of a right angled triangle. The length of a hypotenuse can be found using the Pythagorean Theorem. This states that in a right angled triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the other two sides. This means that to find the length of the hypotenuse, you need to know the lengths of the other two sides.

Where can you find the hypotenuse of a right triangle?
the hypotenuse is the side of the right triangle that is opposite of the 90 degree angle. To figure out the length of the hypotenuse you can use a2 + b2 = c2 (if you know the length of the other two sides) If you don't that you can probably use the sine or the cosine equation. (as long as you know at least one of the angles)
How do you find the length of the hypotenuse for a right triangle?
Use Pythagoras' theorem: a2+b2 = c2 whereas a and b are the sides of the triangle with c being its hypotenuse or longest side
