Answer:
I don't know I'm testing myself now
Step-by-step explanation:
<span>In a 30-60-90 triangle the side opposite the 30 degree angle is half the length of the hypotenuse.
The shorter leg is </span>the side opposite the 30 degree angle, therefore
the shorter leg = 30/2 = 15
<span>By the Pythagorean theorem
</span><span>the longer leg = </span>√(30² - 15²) = √(900-225) = √675 = 15√3 ≈ 25.98 units

Step-by-step explanation:
1. |x-3|=7 and x-3=7
<em>Absoulte rules.</em>
<em>x-3=-7 and x-3=7</em>
<em>Add 3 both sides.</em>
<em>x-3+3=-7+3</em>
<em>Simplify.</em>
<em>-7+3=-4</em>
<em>x=-4</em>
<em>x-3=7</em>
<em>Add by 3 both sides.</em>
<em>x-3+3=7+3=10</em>
<em>x=10</em>
<em>X=-4, and X=10 is the correct answer.</em>

<em>2. |x|-3=7</em>
<em>Add by 3 both sides.</em>
<em>|x|-3+3=7+3</em>
<em>Simplify.</em>
<em>7+3=10</em>
<em>X=10</em>
<em>X=-10 and X=10 is the correct answer.</em>
