QUESTION POSTED AT 16/04/2020 - 07:17 PM

It just means that the angles i and r are congruent
ROQ is 124
so 124 is split in half by line OP
124/2=62
angle r=angle i=62 degrees
now
ROK
we see that the other side is a right angle
so POK must be a right angle as well

POR+ROK=POK=90
angle r=62=POR
so
62+ROK=90
minus 62 both sides
ROK=28 degrees

you forgot to account for angle LOQ in your equation
or maybe you should do 56/2 since it is a bisector

anwya, ROK=28 degres

### At a raffle, 1000 tickets are sold for \$5 each. There are 20 prizes of \$25, 5 prizes of \$100, and 1 grand prize of \$2000. Suppose you buy one ticket. 1. Use the table below to help you construct a probability distribution for all of the possible values of X and their probabilities. 2. Find the mean (expected value) of your net gain X, and interpret what this value means in the context of the game. 3. If you play in such a raffle 100 times, what is the expected value of your net gain? (Hint: Use your answer from #2.) 4. What ticket price would make it a fair game?
