45 divided by 9 is 5 so 5 times 2 is 10. So theirs 10 girls at the park
1 and 2 are right because one has adjacent. 2 vertical angles. Vertical angles mean the same plane and adjacent means two sides of an X.
Multiple 3 by 7 it would be 21 so 21 over 8 evaluate it .it will be2.625 the answer is 2.625 hope this helps you good luck

What you have presented is called a cyclic quadrilateral. A cyclic quadrilateral is a 4 sided figure whose angles (4 of them) all touch the circumference of a circle.
Here's what you want to know. Two angles that are opposite each other are supplementary (they add to 180 degrees)
Equation
x + 80 = 180 Subtract 80 from both sides.
Solution
x + 80 - 80 = 180 - 80 Combine
x = 100
Answer
x = 100
