Exterior angle of a triangle of the sum of two opposite interior angles.
So I see a typo in your question
The way to do this is
Exterior angle= two opposite interior angle s
Or exterior = x+ another interior
Find x
And then
X+ another interior+ y= 180
Solve for y coz you already found x
(Sum of 3 angles of a triangle= 180°)
An exterior angle of a triangle is 15°& one of the interior opposite angle is 35° find the other two angles of a triangles
