On a baseball field, home plate consists of three right angles and two other angles that are congruent. The three right angles are shown in the diagram as ZA, ZB, and ZC. The sum of the interior angles of a polygon can be
found by using the formula (180n - 360)", where n is the number of sides. Find the measure of each nonright angle.

An oil exploration company currently has two active projects, one in asia and the other in europe. let a be the event that the asian project is successful and b be the event that the european project is successful. suppose that a and b are independent events with p(a) = 0.2 and p(b) = 0.8. (a) if the asian project is not successful, what is the probability that the european project is also not successful? (b) what is the probability that at least one of the two projects will be successful? (c) given that at least one of the two projects is successful, what is the probability that only the asian project is successful? (round your answer to three decimal places.)
