Answer 2

Do you have the pic of this?

Answer 3

With any inscribed quadrilateral, the opposite angles add to 180 degrees

Answer 4

so i can just say that the answer is 90 degrees?

Answer 5

angle O + angle Q = 180

use that to find angle O

Answer 6

first you'll have to find x

Answer 7

idk how

Answer 8

add the expression for angle O to the expression to angle Q

Answer 9

set that equal to 180

solve for x

Answer 10

(2x)+(2x+4) (y)+(3y+8) ?

Answer 11

just the first part of that

Answer 12

(2x)+(2x+4) = 180

solve for x

Answer 13

idk how to solve for x!

Answer 14

deos x equal 44?

Answer 15

have a look at this page

Answer 16

yes, x = 44

Answer 17

now use that to find angle O
