What is the best estimate of the measure of the angle shown?

65°

Step-by-step explanation:

When an angle measures less than 90°, then it is called the acute angle.

When an angle measures exactly 90°, then it is known as the right angle.

And, when an measures greater than 90° but less than 180 degree, then it is known as the obtuse angle.

In the given picture,

27° and 65° are acute angles. Whereas, 92° and 138° are obtuse angles.

So, by observation, the angle that is given here is more closer towards the right angle (90°).

Therefore, the angle is 65°.
