Answer:


110° = x

Step-by-step explanation:

According to the Exterior Angles Theorem, which states that the external angle measurement of a triangle is greater than any of the distant internal angle measurements, the remote interior angles and the exterior angle are OPPOSITE each other, so you set them equal to each other:

°45 + 65° = x

110° = x

I am joyous to assist you anytime.

Answer:

x = 110°

Explanation:

The external angle of a triangle is equal to the sum of the 2 opposite interior angles.

x is an external angle to the triangle, thus

x = 65° + 45° = 110°
