A ship is sailing east. At one point the bearing of a submerged rock is at 45 degrees 20 minutes. The ship sails for 15.1 miles and then the rock is at at a bearing of 306 degrees 41 minutes. What the distance of the rock at the later point?

I need help identifying the sides of this word problem: Mr. Clark is finding his distance to a building across the river. He makes a turn of 90 degrees, measures off 45 meters, and finds the acute angle to be 80 degrees. Write the formula that shows about how far he is from the building. When...

I learned how to do this problem in Geometry... but I just can't get it right now. Or at least, the Algebra is too complex for me. Anyway, here's the problem, then I will tell you how far I got. Using a sextant, a surveyor determines that the angle of elevation of a mountain peak is 35 degrees....

Lines a1 and a2 in two-dimensional space intersect at a point, forming an acute angle A. The slope of a1 is the square root of 3, and cosA=1/7. What is the slope of a2? There are two solutions.
