Question

Slove for x to the nearest tenth

Answer 1

Explanation:

Let me start off by saying that 1 unit side is absolutely useless.

You can translate the 6 unit side downwards, so now we have a right isosceles triangle of 2 equal sides which are 6

The hypotenuse is given here by x.

Applying the Pythagorean theorem i can then say;

`x {}^(2) = 6 {}^(2) + 6 {}^(2)`

`x {}^(2) = 36 + 36`

`x {}^(2) = 72`

`x = √(72) = 6 √(2) = 8.485`

x=8.5

rounded to the nearest 10 :)
