The hypotenuse of a right triangle is three times the length of one of its legs. The length of the other leg is four feet. Find

andre [41]

Hello!

It is given information that this triangle is a right triangle, meaning that the Pythagorean Theorem can apply here.

$a^2+b^2=c^2$

We can set the length of a leg as an unknown variable $x$ .

$x^2+4^2=(3x)^2$

Remember that it is the whole $3x$ term being squared, meaning that it'll simplify to $9x^2$ , not $3x^2$ .

$x^2+16=9x^2$

$8x^2=16$

$x^2=2$

$x=\sqrt{2}$

This means we can plug back in to find the sides.

The hypotenuse would be $3\sqrt{2}$ , or 4.2.

And the legs would be 1.4 and 4, respectively.

Hope this helps!
