3 0

Answer:

Step-by-step explanation:

x + x + x = xxx

=> 3x = x³

=> x³ - 3x = 0

=> x(x² - 3) = 0

=> x(x² - (√3)²) = 0

using a² - b² = (a + b)(a - b)

= x(x + √3)(x - √3) = 0

=> x = 0 , -√3 , √3

x = 0 , ±√3

Check picture below, solve for "x" and "y"

unless you've already covered the 30-60-90 triangle, then check your book on them, to see the ratios, using the 30-60-90 ratios is simpler

Find the missing side of the right triangle

o-na [289]

Answer:

<h2>1</h2>

Step-by-step explanation:

Use the Pythagorean theorem:

$leg^2+leg^2=hypotenuse^2$

We have

$leg=3,\ leg=x,\ hypotenuse=\sqrt{10}$

Substitute:

$3^2+x^2=(\sqrt{10})^2$

$9+x^2=10$ <em>subtract 9 from both sides</em>

$9-9+x^2=10-9$

$x^2=1\to x=\sqrt1\\\\x=1$
