The new cost of the book is the old cost plus the of :
Since:
We have the following:
Then, the new price of the book is:
Answer:
Step-by-step explanation:
Mes ∠ O = mes (arc PQR/2)
mes ∠ Q = mes (arc POR/2)
arc PQR + arc POR = 360°
arc PQR/2 + arc POR/2 = 180°
THEN:
mes ∠ O + mes ∠ Q = mes(arc PQR/2) + mes(arc POR/2) = 180°
∠ O + ∠ Q = 180° are supplementary
