Trig equations to solve! A lighthouse is built on the edge of a cliff near the ocean, as shown in the accompanying diagram. From a boat
located 200 feet from the base of the cliff, the angle of elevation to the top of the cliff is 18º and the angle of
elevation to the top of the lighthouse is 28°. What is the height of the lighthouse, x, to the nearest foot?

Christine wong has asked dave and mike to her move into a new apartment on sunday morning. she has asked them both, in case one of them does not show up. from past experience, christine knows that there is a 40% chance that dave will not show up and a 30% chance that mik a. what is the probability that both dave and mike will show up? (round your answer to 2 decimal places.) b. what is the probability that at least one of them will show up? c. what is the probability that neither dave nor mike will show up? (round your answer to 2 decimal places.)e will not show up. dave and mike do not know each other and their decisions can be assumed to be independent.
