The measures of the 2 acute angles of a triangle are in the ratio of 1 : 8. What arethe measures of the 2 angles?	Answers
A) 20°  B) 80°  C) 110°  D) 120°  E) 140°
If the ratio of the two angles is 1:8, then the measures of two angles can be written as x and 8x. Also the two acute angles of a triangle is equal to 90°. Hence   x + 8x = 90   9x = 90   x = 10   Measures of the two acute angles are   x = 1 × 10 = 10°   8x = 8 × 10 = 80°   80°
