Question

In ∆DEF, the measures of the angles D, E, and F, respectively, are in the ratio 2:4:4. What are the measures of the angles?

Answer 1

Answer:

Angle D = 2×18= 36°

Angle E = 4×18=72°

Angle F = 4×18=72°

Step-by-step explanation:

D:E:F = 2x:4x:4x

2x+4x+4x =180. (Angle Sum)

10x = 180

x=180/10=18°
