Question

The measures of the angles of DEF are in the ratio 2:4:4. What are the measures of the angles?

Answer 1

The technique I use is add up the numbers in the ratio. You get 2 + 4 + 4 = 10. Now to find the angles, you have to find the fraction of each number in the triangle. So
`(2)/(10)* 180 = 36` . Since the other two angles are 4 and 4, which are two times of 2, we can say the other two angles are 72 degrees each.
