Question

In a triangle, an exterior angle at a vertex is 105" and one of its interior opposite angle is 55'' . Find the angles of the triangle
​

Answer 1

Answer:

Step-by-step explanation:

Exterior angle of a triangle = 105 deg.

So its supplementary angle = 75 deg.

One interior angle = 55 deg.

So the other interior angle = 105–55 = 50 deg,
