The ratio of the measures of three angles in a triangle is 2:9:4. find the measures of the angles.
Let, the multiple of ratio be x
sum of all angle of triangle : 180°
2x + 9x + 4x = 180°
15x = 180°
x =
x =
x =
x = 12°
measures of angle A = 2x
=
=
measures of angle B = 9x
=
=
= 108°
measures of angle C = 4x
=
=
