A. and
are congruent because they are opposite to one another across the intersection of lines C and D. (We call
and
a "vertical angle pair".)
B. For the same reason and
are congruent, we know that the angles with measures
and
are also congruent. This means
, which we can solve for
.
C.
While vertical angle pairs are congruent, adjacent angle pairs are supplementary. This means that and the measure of
(or
) add to 180 degrees. Similarly,
and the measure of
(or
) also add to 180 degrees.
With , we find
Step-by-step explanation:
Since we have given that
Number of green tickets =3
Number of yellow tickets = 4
Number of purple tickets = 3
Total number of tickets = 3+4+3=10
Now,
As we know that Pedro select a ticket and replace it and then select another ticket , total number of outcomes will never change it will be 10 only for each case.
Probability that he chooses a yellow ticket and then a purple ticket is given by
