It is 7.62 units of length, approx.

32 +82 =9+64=73 So the hypotenuse is of length square root of 73

Using Pythagoras' theorem for a right angle triangle the hypotenuse works out as the square root of 72 which is about 8.485 units to 3 decimal places

There's no such thing as the "length of a 30-60-90". The ratios of the lengths of the legs of such a triangle to the length of the hypotenuse are 1/2 and 1/2(sqrt(3).

The length of the hypotenuse of a right triangle that has a base of 3 feet and a height of 12 feet is: 12.37 feet.

If both legs of a right triangle are the same, then it forms what is known as a "45-45-90 triangle". In this type of triangle, the hypotenuse is always √2 times more than the legs. So in this problem, with legs 3cm and 3cm, the hypotenuse is 3√2cm, or 4.243cm

1.HyL Theorem (Hypotenuse-Leg) - if the hypotenuse and leg of one triangle is congruent to another triangle's hypotenuse and leg, then the triangles are congruent. 2.HyA (Hypotenuse-Angle) - if the hypotenuse and angle of one triangle is congruent to another triangle's hypotenuse and angle, then the triangles are congruent. 3.LL (Leg-Leg) if the 2 legs of one triangle is congruent to another triangle's 2 legs, then the triangles are congruent. 4.LA (Leg-Angle) if the angle and leg of one triangle is congruent to another triangle's angle and leg, then the triangles are congruent.

The length of the hypotenuse is 5

The formula to find the hypotenuse of a right triangle is a2+b2=c2. c being the hypotenuse, a and b being the legs. So, 42+32=c2. 16+9=c2. 25=c2. c=5. The hypotenuse is 5.

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.

32 +82 =9+64=73 So the hypotenuse is of length square root of 73

25. 7, 24, 25 is a Pythagorean Triangle, just as 3, 4, 5 is

Not entirely. You already know that the hypotenuse is only in right triangles, and what it is, right? It's (the two legs)^2=hypotenuse^2. So, for example, if the two legs were to be 3 and 5, it would be 3^2+5^2 which would be 36. But that is the squared answer, so you have to square root it to get 6. Understand!!?
