Answer 1

Try to think about it logically. Look at #2.
The entire circle is 161 and the degrees within the angle is 67. We know that it's an acute angle so it's less than 90 degrees.

For #1, you can see it's 238 degrees all the way around. This is also an acute angle so x is less than 90 degrees. If it's 238 all the way around, than that means half of the circle is 238/2 = 119(119 = each half of the circle)
