Question
Write a Pythagorean Triplet whose one member is 15
Answer
A Pythagorean triplet is found in right angled triangle. So right now in the question we know that one of the member is 15. In a Pythagorean triplet we have base, height and hypotenuse. So the formula for each is ⇒
- Base ⇒ 2m
- Height ⇒ m² - 1
- Hypotenuse ⇒ m² + 1
So now we will cross check which part of the Pythagorean triplet can 15 be in.
Base
2m = 15
m = 15 ÷ 2
m = 7.5
∴ 15 isn't the base because the numbers in the Pythagorean triplet is always a whole number.
Height
m² - 1 = 15
m² = 15 + 1
m² = 16
m = √16
m = 4
∴ 15 could be the height because while solving the equation the value of 'm' is not in decimal and has a whole value.
Hypotenuse
m² + 1 = 15
m² = 15 - 1
m² = 14
m = √14
∴ 15 isn't the hypotenuse because the numbers in the Pythagorean triplet is always a whole number.
∴ 15 is the base.
With the value of 'm', we will find the base and hypotenuse.
Base
2m
2 × 4 = 8
∴ The Base is 8.
Height
m² - 1
4² - 1
16 - 1
15
∴ The height is 15.
Hypotenuse
m² + 1
4² + 1
16 + 1
17
∴ The hypotenuse is 17.
∴ The Pythagorean Triplet whose one member is 15 is ⇒ 8, 15 and 17.
