The angles of a triangle are in the ratio 3: 4 : 2. Find the measurement of the 3 angles of triangle.
Choose the correct choice from the following answers
A) 40°	B) 25°	C) 30°	D) 75°	E) 90°
If the ratio of the three angles is 3:4:2, then the measures of these angles can be written as 3x, 4x and 2x. Also the sum of the three interior angles of a triangle is equal to 180°. Hence   3x + 4x + 2x = 180   Solve for x   9x = 180   x =20   The measures of the three angles are   3x =3 x20=60°   4x = 4 × 20= 80°   2x = 2 × 20 = 40°   40°
