This is only my opinion. I could be wrong.
My guess is:
Somebody else used that book before you, maybe last year or
the year before, and it was somebody who didn't mind writing
in his book.
One day he didn't have time to write down the homework in his
assignment notebook, so he just circled the homework problems
in his textbook.
H. Looks like you circled it, so yes, you’re right!
First, you calculate the inner corners of the triangle. These two are 115 -> 65 and 304 -> 56, because a straight line is 180 degrees and a circle is 360 degrees. Then you can calculate the third corner: 59 degrees. Then, since a staight line is 180 degrees, you can calculate the answer. 180-59= 121
Answer: 121 degrees
Answer:
about 137 degrees
