Question

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

Answer 1

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.
