Question

9. An exterior angle of a triangle is 105º and its two interior opposite angles are equal. Each of these equal angles is​

Answer 1

Answer:

Exterior angle = Sum of interior opposite angle

Both interior angle are equal.(given)

105=x+x

105=2x

105/2=x

52.5=x

Thus each angle is of 52.5°

Answer 2

Answer:

let the two angles be X & Y

X+Y =105°

X+X= 105 ( Both are equal)

2X =105

X =105/2

X = 52.5
