How to solve 45 45 90 triangle given hypotenuse?

1 answer:

4 0

From the Special Triangle Theorem, the hypotenuse is equal to the side lengtht times the Sqrt(2).
So hypotenuse H = xSqrt(2), x=H/Sqrt(2).
Using numbers, if H = 7, then x = 7/Sqrt(2) = 7Sqrt(2)/2 to rationalize it.

Crazy boy [7]

Answer:

$x=-10$ or $x=4$

Step-by-step explanation:

$ax^2+bx+c=0$

$x^2-6x-40=0$

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

$x=\frac{-6\pm\sqrt{6^2-4(1)(-40)}}{2(1)}$

$x=\frac{-6\pm\sqrt{36+160}}{2}$

$x=\frac{-6\pm\sqrt{196}}{2}$

$x=\frac{-6\pm14}{2}$

$x=-3\pm7$

$x=-10$ or $x=4$
