1/5 + 1/4.....lowest common denominator is 20
4/20 + 5/20 = 9/20 <==
Answer:
x=52
y=25
z=90
Step-by-step explanation:
x= 180-38-90=52
y= 180-(65+52)-38=25
z=180-65-25=90
To find this you can subtract it by taking the improper fraction 1 1/2 and turning into a mixed number which will be 3/2. This make a it easier to subtract. You subtract 3/2 and 1/4 which you will get 5/4 which is also 1 1/4. So 1 1/2 is 1 1/4 greater than 1/4.
Answer:
opposite angle of trapezoid is supplementary
<Z+<X=180°
<X=180°-72°
<x=108°
is your answer
Okay, so first you are going to decide whether to solve for x or solve for y. I am going to solve for x. In order to do so, you must get x by itself.

![2x=y-6[ [tex]3x-4y=-4](https://tex.z-dn.net/?f=2x%3Dy-6%5B%20%5Btex%5D3x-4y%3D-4)

The next step is to set both equations equal to each other in order to find y.
\frac{y-

6}{2} [/tex]
So now you know that y=-2. The next part is substitution. All you have to do is pick on of the equations and plug in the y value to get the x value.
So your answer to the question is (-4,-2). I hope I've helped you understand how to solve these types of problems. If you have any questions, don't hesitate to ask.
