Answer:
x = 136
Step-by-step explanation:
Opposite angles of a quadrilateral in a circle are supplementary.
50,52,53,55,56,57,58,59,60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75,76,77,78,79,80,81,82,83,85,86,87,88,89,90,91,92,94,95,96,97,98,99,100,101,102,103,105,106,107,108,109,110,111,112,113
First subtract the C to move it to the other side
c-P=b+4a
Then subtract the 4a as well
4a-c-p=b
c. x=8
make me a brain list.
