Question

5. In a triangle one of the exterior angle is 105º. One of the interior opposite angle is 75º.
Find the measure of all the angles of the triangle.​

Answer 1

Explanation:

here is your answer hope your doubt is cleared

Answer 2

We know,

sum of interior angles= exterior angle.

Let one of the interior opposite angle (which is not given) be x

Therefore,

75+x=105

x=30°

Therefore the two opposite interior angle are 75° and 30°

Therefore, the third side will be

180-(75+30). [Angle sum Property]

180-105

=75°

Therefore the three angles of the triangle will be 75, 75, 30...
