Answer:


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 ^-^

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
