Let's do this question in triangle pick arm angle is equal to 60 degree angle, Q is equal to 40 degree,
then the exterior angle formed by producing cure is equal to.
All right, so let's produce cure and we get an exterior angle over here.
That's angle p, r e and you tell me what P R is equal to.
It's a very basic question, but it'll help you solidify your foundation.
Tobii, the exterior angle property of triangles.
We know that b r e is equal to angle B plus angle Q, right.
Because the exterior angle is equal to the sum of the interior opposite angles.
Therefore angle p r E is equal to 60 plus 40, which gives you one hundred degree.
And the correct answer is option C.
