(2x-24)/8
the only way to simplify it is divide every number by 2
(x-12)/4=(1/4)x-3
Step-by-step explanation:
Using Pythagoras theoram,
AC²= AB²+BC²




The answer is b or the second choice available
<span>It is important to know that the sum of the three angles inside a triangle add up to 180 degrees. So then we get the following by adding up all three provided angle measures:
3x + (2x + 20) + (4x - 20) = 180
Some algebraic manipulation follows:
3x + 2x + 20 + 4x - 20 = 180
9x = 180
x = 180/9 = 20
The value of x is 20 degrees.</span>
I graphed the 4 points and connected the dots. (Sorry I'm not able to show this)
I then realized it was some type of trapezoid however, I wasn't sure which kind of trapezoid (regular or isosceles) so I googled the properties of both and concluded that it makes a regular trapezoid.
