The measures of the 2 acute angles of a triangle are in the ratio of 3 : 7. What arethe measures of the 2 angles? Choose the correct choice from the following choices:  A) 20°  B) 70°  C) 110°  D) 63°  E) 140°
If the ratio of the two angles is 3:7, then the measures of two angles can be written as 3x and 7x. Also the two acute angles of a triangle is equal to 90°. Hence   3x + 7x = 90   10x = 90   x = 9   Measures of the two acute angles are   3x = 3 × 9 = 27°   7x = 7 × 9 = 63°   63°
