Two of the three interior angles of triangle M are 40 ° and 75 °. One of the three exterior angles of triangle N is 140 °. Of triangles M and N are similar, what are the other two exterior angles of triangle N?

Ab and bc are tangent to circle d. find x is ab = 3x + 8 and bc = 26. find x

At store a, erasers are sold individually. the cost y of x erasers is represented by the equation y=0.75x. the costs of erasers at store b are shown in the graph.

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.)
