Question

One angle of a triangle measured 70 the other two angles are in a ratio of 7 : 15 what are the measures of those two angles

Answer 1

35°, 75°

Explanation:

Let the measures of the remaining two angles be 7x and 15x

By interior angle sum Postulate of a triangle.

70° + 7x + 15x = 180°

22x = 180° - 70°

22x = 110°

x = 110°/22

x = 5°

7x = 7*5° = 35°

15x = 15*5° = 75°
