First, we must follow PEMDAS. (Parenthesis, exponents, division, multiplication, addition, and subtraction.).
We do what's in the parenthesis first.
9+9(2+4)÷3-2.
2+4=6.
Now our problem looks like this;
9+9(6)÷3-2
OR
9+9×6÷3-2.
Anything in a parenthesis with no sign next to it, like this; 8(2), just means multiplication, so it would look like this: 8×2.
Next, we do all the multiplication in our problem.
9+9×6÷3-2.
9×6=54.
Now our problem looks like this;
9+54÷3-2.
Next, we do the division.
9+54÷3-2
54÷3=18.
Now our problem looks like this;
9+18-2.
Next, we do the addition.
9+18-2
9+18=27
Now it looks like this;
27-2.
Finally, we subtract.
27-2=25.
Your final answer is 25!
Have a nice day! :)
Given:
m(ar QT) = 220
m∠P = 54
To find:
The measure of arc RS.
Solution:
PQ and PT are secants intersect outside a circle.
<em>If two secants intersects outside a circle, then the measure of the angle formed is one-half the positive difference of the measures of the intercepted arcs.</em>


Multiply by 2 on both sides.


Subtract 220 from both sides.


Multiply by (-1) on both sides.


The measure of arc RS is 112.

this seems too easy so I'm probably wrong but thats how I read the question
