Answer:

B

Step-by-step explanation:

If we understand 2 properties of isosceles trapezoids, then we can solve for x and y easily.

First, the two sides, "2x-13" and "x-3" are equal, as shown also by red line.

So, we equate them and find x first. Shown below:

2x-13=x-3\\2x-x=-3+13\\x=10

Now, another property is:

Any lower base angle is supplementary to any upper base angle. That means the angle y is supplementary to "3y-4". Supplementary means that if we add up the two angles, it will be 180 degrees. So:

y+3y-4=180\\4y=180+4\\4y=184\\y=46

From the answer choices, answer choice B is right

30x(x-3) multiply please
krek1111 [17]
You distribute the 30x to the equation in parenthesis

So basically you are doing (30x*x)+(30x*-3)
So you get 30x^2-90x

Hope this helps!
