The measures of the 2 acute angles of a triangle are in the ratio of 3 : 6. What arethe measures of the 2 angles?
Choose the correct answer:
A) 20°
B) 70°
C) 60°
D) 120°
E) 140°
If the ratio of the two angles is 3:6, then the measures of two angles can be written as 3x and 6x. Also the two acute angles of a triangle is equal to 90°. Hence   3x + 6x = 90   9x = 90   x = 10   Measures of the two acute angles are   3x = 3 × 10 = 30°   6x = 6 × 10 = 60°   60°
