Question

Find the missing side of each triangle

I can’t remember the steps to doing this/the formula, an explanation would be great thanks!

Answer 1

sqrt(40) or approx. 6.324555

Explanation:

a^2 + b^2 = c^2 (Pythagorean Theorem)

6 is a, 2 is b, and x is c, or the hypotenuse.

Plug in the values

6^2 + 2^2 = x^2

Simplify

36 + 4 = x^2

40 = x^2

Square root both sides

sqrt(40) = x

Answer 2

Explanation:

Pythagorean theorem

a^2+b^2=c^2

2^2+6^2=x^2

4+36=x^2

40=x^2

`√(40)=x`

`2√(10)`
`=x\\`

Hope that helps :)
