Answer:
Step-by-step explanation:
5. The opposite angles of a cyclic quadrilateral sum to 180 so
9y + 5 + 18x + 4 = 180 and
9y - 9 + 21x + 6 = 180
Solve this system to find x and y.
7. Solved in the same way.
Have to go right now so i cant help you any further.

YOU CAN EVEN WRITE IT IN THE FRACTION FORM .
BE REMINDED THAT <> CHANGE SIGN WHEN YOU DIVIDE OR MULTIPLY A NEGATIVE NUMBER ONLY.
HOPE THIS HELPS
Answer:
Step-by-step explanation:
givens
x1 = 3
x2 = 4
y1 = 4
y2 = 7
formula
d = sqrt( (x1 - x2)^2 + (y1 - y2)^2 )
solution
d = sqrt( (3 - 4)^2 + (4 - 7)^2 )
d = sqrt ( 1 + 3^2)
d = sqrt( 1 + 9)
d = sqrt( 10)
