Question

HELP PYTHAGOREAN THEOREM plssss ASAP

Answer 1

`2√(51)`

Explanation:

first, you have to look pythagoras theorem (in picture)

then; x² + 14² = 20²

x² + 196 = 400

x² = 204

x =
`√(204)` =
`2√(51)`

Hope this helps ^-^

Answer 2

Given:

• Hypotenuse= 20
• Side 1= 14

To find:

The length of the unknown side ( x )

Solution:

We'll have to use pythagoras Theorem.

`\huge\boxed{\sf{Formula: {a}^(2) + {b}^(2) = {c}^(2) }}`

In this question hypotenuse is given so we'll have to subtract.

Let the unknown be "x"

`{c}^(2) = {a}^(2) - {b}^(2)`

`{x}^(2) = {20}^(2) - {14}^(2)`

`x = 204`

`{x}^(2) = √(204)`

`x = 14.28285686`

`\large\boxed{\sf{x = 14.3 \: (nearest \: tenth)}}`

Hence, the unknown side of the given triangle is 14.3
