Question

the exterior angle of a triangle obtained by producing one side is 126 degree and the measure of one co interior opposite angle is 48 degree find the measuring of other angle​

Answer 1

Answer:

the exterior angle of a triangle obtained by producing one side is 126 degree and the measure of one co interior opposite angle is 48 degree find the measuring of other angle

Step-by-step explanation:

Let the interior angles be x and 3x

We know that exterior angle of triangle is equal to sum of interior opposite angles.

⇒x+3x=80

∘

⇒4x=80

∘

⇒x=20

∘

So the angles are

x=20

∘

3x=3×20

∘

=60

∘

So option C is correct.
