Step-by-step explanation:
Answer:
a its parallel
b its parallel
c its parallel
Step-by-step explanation:
i dont know it's about parallel
Ok so there's 5 sides
let's find interior angle sum
formula is S=180(n-2)
n in this case is 5 since there are 5 sides
S=180(5-2)
S=180(3)
S=540
so now add the 5 angle lengths up to 540
5x+2+10x-3+7x-11+13x-31+8x-19=540
43x+-62=540
+62 +62
43x=602
divide both sides by 43
x=14!!!!!
First, you have x+y= 3k, x-y= k and what you need to do now is eliminate the y's because they have the same sign (- and +). So now you have x= 3k, x=k. You so then you add the x with the other x (2x) and the 3k with the k (4k). Now you have 2x = 4k , which is the same as x = 2k. Now that you now x in terms of k, you can put it in the very first system, like this: 2k+y=3k, 2k-y=k. If you solve them, first one and then the other, you will get the same result: y=k.
So, you can say that x=2k and k=y.
Hope that was helpful, have a good day! :))
