The opposite angles in a cyclic quadrilateral are supplementary. i.e., the sum of the opposite angles is equal to 180˚
So using theorem we find that
∠A+∠C = 180
x + 108 = 180
x = 180 - 108
x = 72
∠B+∠D = 180
88 + y = 180
y = 180 - 88
y = 92

3 pen + 2 pencil = .47
2 pen + 3 pencil = .38
2(3pen + 2 pencil = .47)
-3(2pen + 3 pencil = .38)
6 pen + 4 pencil = .94
-6 pen - 9 pencil = -1.14
- 5 pencil = -.2
pencil = .04
3pen + 2(.04) = .47
3pen + .08 = .47
3 pen + .08 - .08 = .47 -.08
3 pen = .39
pen = .13
Pen = 13 cents and pencil = 4 cents
Answer: 3
Step-by-step explanation:
