option A - 55 each
option B - 50 and 60
option C - 65​

Answer 1

Answer:

Answer is attached here

Step-by-step explanation:

Option A. 55 each is the correct answer

Answer 2

Step-by-step explanation:

ANSWER:

Let the measure of each of the two equal interior opposite angles of the triangle be x.

In a triangle, the exterior angle is equal to the sum of the two interior opposite angles.

∴ x + x = 110°

⇒ 2x = 110°

⇒ x = 55°

Thus, the measure of each of these equal angles is 55°.

Hence ,the correct answer is option A is correct..
