Answer:
930
Step-by-step explanation:
1) Once upon a time there was a bored kid in class who invented a super cool formula
This formula goes like this:
n(n+1)
where n= the sum of the first n numbers in a series
so
30(30+1)=30(31)=930
930
We know that since a diameter splits a circle in half, the arcs EF, FG, and GH must add up to 180°, half the measure of a full circle. We can then use the arc addition property to create an equation using the information we know. This equation would be (10x + 8) + 67 + 11x = 180. This can be simplified to x = 5. Therefore, the value of x is 5. Now, we can simply plug in the value of x into the expressions for EF and GH. This means that the measure of EF is 58° and the measure of GH is 55°.
Hope this helps!

so it's not a match. Well, what pattern is that property? Symmetric property of equality says that: If A = B, THEN B = A, i.e the order does not matter, you can interchange the LHS (left-hand side), and the RHS (right-hand side). "If AB+BC = 24 and AB = 10, THEN 10 + BC = 24 is an example of the ?"
