Given:
To find:
The length of the unknown side ( x )
Solution:
We'll have to use pythagoras Theorem.
[tex]\huge\boxed{\sf{Formula: {a}^{2} + {b}^{2} = {c}^{2} }}[/tex]
In this question hypotenuse is given so we'll have to subtract.
Let the unknown be "x"
[tex] {c}^{2} = {a}^{2} - {b}^{2} [/tex]
[tex] {x}^{2} = {20}^{2} - {14}^{2} [/tex]
[tex]x = 204[/tex]
[tex] {x}^{2} = \sqrt{204} [/tex]
[tex]x = 14.28285686[/tex]
[tex]\large\boxed{\sf{x = 14.3 \: (nearest \: tenth)}}[/tex]
Hence, the unknown side of the given triangle is 14.3
