The angles of triangle are in the ratio 3:4:5. Find the measure of each angle.

Answer»

ANSWER:

since the sum of the angles in a triangle is equal to 180 degrees, this MEANS that: 3X + 4x + 5x = 180 degrees which means that 12x = 180. divide both SIDES of this equation by 12 and you get X = 180 / 12 = 15 degrees.
