I assume you are looking for arc RSQ, since you already now the angle RSQ.
Arc RSQ is 312 degrees.
Since you know angle RSQ, the arc that it creates is twice the angle.
24 x 2 = 48
Arc RSQ is the entire circle (360 degrees) except for that 48 degrees.
360 - 48 = 312
Your answer would be -16.
Answer:
A
Step-by-step explanation:
The opposite of point A is 9
Because the opposite of -9 is 9
And the opposite of 9 is -9
Answer: 
Step-by-step explanation:
This is a problem you need to solve using logs. When you use logs you can "pull" the exponents down in front of the log to get a new equation that looks like this: 2x^3 + x^2 log 81 = 6x - 3 log 27. Now divide both sides by log 81 and 6x - 3 simultaneously to get (2x^3 + x^2)/(6x - 3) = (log 27)/(log 81). If you do the log math on the right side you get .75. Now multiply both sides by 6x-3 to get 2x^3+x^2 = .75(6x-3). If you distribute that out on the left side you'll get 2x^3+x^2=4.5x-2.25. Now move everything over to the left side and set the whole thing equal to 0: 2x^3+x^2-4.5x+2.25=0. When you solve for x, you are in essence factoring, so do this by grouping: x^2(2x+1)-2.25(2x+1). Now finally factor out the 2x+1 to get (2x+1)(x^2-2.25). You're not done yet though cuz you need to solve each of those for x: 2x+1=0, and x= -1/2; x^2=2.25, and x=+/- 1.5. So all the values for x here are -1/2, 1.5, and -1.5
