A 30-60-90 triangle has its longer leg of length 7.8 what is the length of the shorter of the two legs?

The shorter leg is 1/2 of the hypotenuse, while the longer leg is (sin60°) times the hypotenuse or about 0.866 times as long. (7.8/0.866) gives the hypotenuse as 9.0 and 9.0/2 = about 4.5 units
or use the tangent ratio:
7.8/tan 60° = 4.5033321 or about 4.5 in length

He length of the longer leg of a right triangle is 3ft more than three times the length of the shorter leg. The length of the hypotenuse is 4ft more than three times the length of the shorter leg. Fin?
The length of the longer leg of a right triangle is 3ftmore than three times the length of the shorter leg. The length of the hypotenuse is 4ftmore than three times the length of the shorter leg. Find the side lengths of the triangle.
How do you find the hypotenuse and longer leg of a 30 60 90 triangle?
If you have the shorter legs length, then for the hypotenuse, just multiply the shorter leg by 2. For the longer leg, multiply the shorter leg by the square root of 3.
Triangle has two sides of length 4 and 15 What value could the length of the third side be?
The third side must be longer than 11 and shorter than 19.
In a 30-60-90 triangle if the shorter leg has length p then the longer leg has length and the hypotenuse has length?
Use the rule that the shortest leg has length p, the other leg has length 2p and the hypotenuse has length p*sqrt(3) Where sqrt(number) if the square root of the number.
How do you find the side lengths of a 20-70-90 triangle?
There are an infinite number of different sets of lengths that will do it. You have to start by choosing the length of one side, and when you do that, here's how to find the others: Shorter leg = (longer leg) x 0.364 Shorter leg = (hypotenuse) x 0.342 Longer leg = (shorter leg) x 2.747 Longer leg = (hypotenuse) x 0.94 Hypotenuse = (shorter leg) / 0.342 Hypotenuse = (longer leg) / 0.94

The hypotenuse of a triangle is 15 feet long The longer of the two legs is three feet longer than the other Find the length of the shorter leg?
The shorter leg is 9 feet long
The hypotenuse of a triangle is 10 feet long The longer of the two legs is two feet longer than the other Find the length of the shorter leg?
The shorter leg is 6 feet long

Does the length of a pendulum effect how it swings?
Yes, the length of a pendulum affects its swing. The oscillation will be longer with a longer length and shorter with a shorter length.
Does the centroid of a triangle divide each median into two segments so that the shorter segment is half the length of the longer segment?
Yes.
What is the length of the shorter leg of a right triangle if the longer leg has a length of 45 and the hypotenuse has a length of 53?
Subtract the squared longer leg's squared length from the hypotenuse's square to obtain the squared shorter leg length. Then find the square root of that answer for your final answer. In other words: 53 squared minus 45 squared equals your squared answer.
What are the characteristics of an isosceles triangle?
Two sides have the same length as each other. The other side may be shorter or longer in length than the other two sides.
What is the ratio between the lengths of the two legs of ab30-60-90 triangle?
The length of the longer leg equals the length of the shorter leg times the square root of three.
Which side of a rectangle is the length?
Either of the longer and shorter sides, but the length is usually the longer side and width is usually the shorter side.
What is the hypotenuse of a triangle is 10 feet long The longer of the two legs is two feet longer than the other Find the length of the shorter leg?
Short leg is 6 feet.
