Answer:

m∠O and m∠Q are supplementary

m∠P and m∠R are supplementary

Step-by-step explanation:

<u>Cyclic quadrilateral</u>:  a quadrilateral drawn inside a circle where every vertex of the quadrilateral touches the circumference of the circle.

<u>Theorem</u>:  Opposite angles in a cyclic quadrilateral add up to 180°

<u>Supplementary angles</u> are two angles whose measures sum to 180°

Therefore, the opposite angles in a cyclic quadrilateral are supplementary:

m∠O + m∠Q = 180°

m∠P + m∠R = 180°

Kenzie has. 4 pages of homework to do. If she can finish 1/3 of a page in one hour how many hours will her homework take?
Maru [420]

Answer:

It will take her 4 1/3 hours

Step-by-step explanation: so you know you needed to  add 4 and 1/3 and you turn the 4 into 4/1 and 1/3 and since it adding you have to have the same denominator and you multiply 1x3 and if you do it on the bottom you have to do it on top so you also do 4x3 and 4x3 is 12 and one 1x3 is 3 and so you don't have to have to do it on the other fraction because now they have the same denominator now and now you add 12/3 + 1/3 and you shall get 13/3 and then you divide 13 divided by 3 and you shall get 4 1/3 and that shall be your answer.

hope it helps you!
