Question

What is the measure?

Answer 1

The answer for this problem: Option C.

Answer 2

We know that because it forms a right angle, BOF is 90 degrees. We also know that FAO and AOB combine to make 90 degrees.

We already know the value of FOA, so subtract that from 90.

90-35=55.

The measure of AOB is C. 55.

Hope this helps!
