Question

one angle of a triangle measures 20 and the other two angles are in a ratio of 3:5 what are the measures of the 2 angles

Answer 1

60 and 100 degrees.

Explanation:

Sum of the other 2 angles = 180-20 = 160 degrees.

3 + 5 = 8

160 / 8 = 20

- so the other 2 angles are:

3*20 = 60 and

5*20 = 100 degrees.
