A submarine dives at a constant speed of 10 m/s at a diving angle measured from the vertical
of 75º. If the submarine starts its dive from the surface, how deep is the front end of the
submarine at the end of a 1-minute dive?

If you have a set of parallel lines a and b cut by transversal x, if angle 1 = 167 degrees, what is angle 4 and why. also what is the measure of angle 5 and why? you need to use the names of the angle relationship and explain.
