Answer:
x = 15
Step-by-step explanation:
the opposite angle of a cyclic quadrilateral sum to 180° , then
6x + 20 + 3x + 25 = 180
9x + 45 = 180 ( subtract 45 from both sides )
9x = 135 ( divide both sides by 9 )
x = 15
Answer:
G) AC = 12
Step-by-step explanation:
5/10 = (x + 5)/(3x + 3)
15x + 15 = 10x + 50
5x = 35
x = 7
AC = 7 + 5 = 12
Rational, or integer. I am not sure sorry
