Salvador places a circular canvas on his A-frame easel and carefully centers it. The top of the easel forms a 30° angle, and $m\angle BC = 22°$. What is $m\angle AB$?

An "arc" in mathematics is a straight line that connects two endpoints. An arc is typically one of a circle's parts. In essence, it is a portion of a circle's circumference.

A curve contains an arc. A circle is the most common example of an arc, yet it can also be a section of other curved shapes like an ellipse.

We have,

The top of the easel forms a 30° angle and m (BC) = 22°.

As per the question,

AD = ED and m

So, m

= 1/2 (180 - m

= 75

and, m

= 1/2(22)

= 11

Then, m

= 75 - 11 = 64

Also, m (AB) = 2 x 64 = 128
