If

and , exactly how long is side ?Explanation:

This difficulty is resolved using the Pythagorean organize

. In this formula and are the legs of the ideal triangle while is the hypotenuse.You are watching: If the legs of a right triangle have length 6 inches and 8 inches

Using the brand of our triangle us have:

### Example concern #2 : exactly how To uncover The length Of The Hypotenuse the A right Triangle : Pythagorean theorem

Explanation:

Therefore *h*2 = 50, so *h* = √50 = √2 * √25 or 5√2.

### Example inquiry #3 : exactly how To discover The length Of The Hypotenuse the A ideal Triangle : Pythagorean to organize

The elevation of a right circular cylinder is 10 inches and also the diameter that its basic is 6 inches. What is the street from a suggest on the leaf of the basic to the facility of the entire cylinder?

Explanation:

The finest thing come do right here is to attract diagram and draw the appropiate triangle for what is being asked. It does not matter where you ar your allude on the base due to the fact that any allude will create the same result. We know that the facility of the basic of the cylinder is 3 inches away from the basic (6/2). We also know the the center of the cylinder is 5 inches native the basic of the cylinder (10/2). For this reason we have a ideal triangle through a elevation of 5 inches and also a base of 3 inches. So using the Pythagorean theorem 32 + 52 = c2. 34 = c2, c = √(34).

### Example inquiry #4 : exactly how To discover The size Of The Hypotenuse the A ideal Triangle : Pythagorean to organize

A appropriate triangle with sides A, B, C and respective angle a, b, c has the adhering to measurements.

Side A = 3in. Side B = 4in. What is the size of next C?

**Possible Answers:**

5

6

25

7

9

**Correct answer:**

5

Explanation:

The exactly answer is 5. The pythagorean theorem claims that a2 + b2 = c2. Therefore in this instance 32 + 42 = C2. Therefore C2 = 25 and C = 5. This is also an instance of the common 3-4-5 triangle.

The lengths the the three sides that a appropriate triangle type a set of consecutive also integers once arranged from the very least to greatest. If the second largest side has actually a length of x, then which of the adhering to equations can be supplied to settle for x?

**Possible Answers:**

(x – 2)2 + x2 = (x + 2)2

(x – 2) + x = (x + 2)

x 2 + (x + 2)2 = (x + 4)2

(x – 1)2 + x2 = (x + 1)2

(x + 2)2 + (x – 2)2 = x2

**Correct answer:**

(x – 2)2 + x2 = (x + 2)2

Explanation:

We space told that the lengths kind a series of consecutive also integers. Since even integers space two devices apart, the next lengths must differ through two. In various other words, the largest side length is two higher than the second largest, and the second largest length is two greater than the smallest length.

The 2nd largest length is equal to x. The second largest size must for this reason be two much less than the largest length. We can represent the biggest length together x + 2.

Similarly, the second largest size is two larger than the smallest length, i beg your pardon we might thus stand for as x – 2.

To summarize, the lengths of the triangle (in regards to x) space x – 2, x, and x + 2.

In order to resolve for x, we can exploit the fact that the triangle is a best triangle. If we apply the Pythagorean Theorem, us can collection up an equation that could be supplied to deal with for x. The Pythagorean Theorem claims that if a and also b space the lengths the the foot of the triangle, and c is the length of the hypotenuse, climate the following is true:

a2 + b2 = c2

In this specific case, the 2 legs of our triangle room x – 2 and also x, due to the fact that the legs room the two smallest sides; therefore, we have the right to say that a = x – 2, and also b = x. Lastly, we have the right to say c = x + 2, due to the fact that x + 2 is the length of the hypotenuse. Subsituting these worths for a, b, and c into the Pythagorean Theorem returns the following:
