Three adjacent angles are at a point. The first angle is represented by x° , the second angle is 20° more than the first, and the third angle is 20° more than the second angle. Find the measurements of all three angles.

The first angle of a triangle is four times the third angle; the second angle is twenty degrees less than three times the third angle. Let the measure of the third angle be C.

Jack and Jill were on the same side of a hill but were 34 m apart. Both were lying on the ground looking up at the peak of a hill. Jill, who is closer to the hill, determined that the angle of elevation to the top was 37 degree. Jack determined that the angle of the elevation to the top from his position was 22 degree. How high is the peak of the hill

Two cruiser warships the Arizona and Baltimore are trying to find the position of an enemy submarine. The USS Arizona detects the sub at an angle of 17 degrees and the USS Baltimore detects the sub at an angle of 23 degrees from its position. If the cruisers are 1324 m away from each other, which ship is closer to the submarine? How far below the surface is the sub?
