Can you help me with these angles please?

11. ∠9 = 100°

12. ∠6 = 80°

13. ∠8 = 80°

14. ∠2 = 80°

15. ∠5 = 100°

16. ∠11 = 100°

Step-by-step explanation:

11. 100°    12. 80°     13. 80°    14. 80°    15. 100°    16. 100°      

Step-by-step explanation:

We know a straight line is 180 degrees and that m∠7 is 100 degrees.

m∠9, m∠5 and m∠11 are 100 degrees

To find m∠6, m∠8, and m∠2 we subtract 100 from 180 and get 80 degrees.

If you fill in all the degrees of the angles, you will notice a zig-zag pattern. That helps when solving these kinds of problems

I hope this helped, please mark Brainliest, thank you!

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
