This is a 45-45-90 triangle which means that the two non-hyptonouse lenghts are the same which means that the bottom lenght of the triangle is also 10 units

We can then use a^2+b^2=c^2 to solve for the last side

so we have

10^2+10^2=x^2

200=x^2

sqrt200=x

and I see that they want an exact answer so you simplify sqrt200 to

10√2

Rational number between -1 and 1<br>

Nonamiya [84]

Answer:

$\dfrac{-1}{2}$

Step-by-step explanation:

We need to find ration numbers between -1 and 1.

Multiplying and dividing both -1 and 1 by 2.

$\dfrac{-1\times 2}{2}=\dfrac{-2}{2}$

and $\dfrac{1\times 2}{2}=\dfrac{2}{2}$

Now, the rational number between -2/2 and 2/2 is $\dfrac{-1}{2}$ .
