My sailboat has a triangular sail that forms a right triangle. the bottom measures 9 yards and it stretches to the top of the mast. the hypotenuse measures 15 yards. how tall is the sail?

Solve the system by the elimination method. 3x - 2y - 7 = 0 5x + y - 3 = 0 to eliminate y, the lcm is 2. which of the following is the resulting equations? 1.3x - 2y - 7 = 0 5x + y - 3 = 0 2.3x - 2y - 7 = 0 -10x - 2y + 6 = 0 3.3x - 2y - 7 = 0 10x + 2y - 6 = 0

Solve: 3x+y=6 4x-2y=18 show all work !

The ratio of the measures of the three angles in a triangle is 2: 9: 4. find the measures of the angels
