1.  9(3)+3 = 27+3 = 30
2. 9(8^{4}) = 9(4096) = 36864
3. 9-6+3 = 6
4. 6(5)+30 = 30+30 = 60
5. 6(8^{3}) = 6(512) = 3072
6. (8^{3})+84 = 512+84 = 596
7. 200+51 = 251
8. 3(18)+18^{2} = 54+324 = 378
9. 12(24)-36 = 288-36 = 252
10. 4(11+90)+10 = 44+280+10 = 334

Determine the following angle measures.<br> mZM=<br> mXL =
fomenos

Angle measures are ∠M = 90° and ∠L = 24°

Step-by-step explanation:

  • Step 1: In the figure, LM is a tangent to the circle N at point M.

Tangents create right angles at the point of contact with a circle.

So ∠M = 90°

  • Step 2: Sum of angles in a triangle is equal to 180°

⇒ ∠L = 180° - (∠M + ∠N) = 180° - (90° + 66°)

         = 180° - 156° = 24°

Given: -1/2x &gt; 6. Choose the solution set.
vazorg [7]
The answer would be B. You multiply the 2 on both sides, getting 12 on the right. Then you divide by -1, and that switches the sign and makes 12 negative.
