Question

alternative . In angle DEF,angle D= 50° and angle E=80° then what is measune of exterior angle DFG
A) 130 B) 100 c) 70° ) 500​

Answer 1

Answer:

A) 130

Step-by-step explanation:

Since the exterior angle of a triangle is equal to the sum of the 2 interior opposite angles ,

Therefore,In ∆DEF,

angle D + angle E = angle DFG

=> 50° + 80° = angle DFG

=> angle DFG = 130°
