Clovis wants to make a surprise visit to his uncle who lives out of town. he purchases an airline ticket for $69. there is a 15% sales tax on the price of the airline ticket. in addition he must pay a baggage fee of $20. when he arrives at the airport, clovis takes a taxi to his uncle's house which is 8 miles from the airport. the taxi fee is $2.50 per mile. if clovis has spent a total of $123.35 for the airline ticket and taxi, at what percent of his fare did clovis tip the taxi driver?

I've been working on this for a few days and i just don't understand, it's due in a few hours. you. the direction of a vector is defined as the angle of the vector in relation to a horizontal line. as a standard, this angle is measured counterclockwise from the positive x-axis. the direction or angle of v in the diagram is α. part a: how can you use trigonometric ratios to calculate the direction α of a general vector v = < x, y> similar to the diagram? part b suppose that vector v lies in quadrant ii, quadrant iii, or quadrant iv. how can you use trigonometric ratios to calculate the direction (i. e., angle) of the vector in each of these quadrants with respect to the positive x-axis? the angle between the vector and the positive x-axis will be greater than 90 degrees in each case. part c now try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
