I hope this helps you
z=3/2
8. (3/2)^3-12.3/2-15
8.27/8-6.3-15
27-18-15
-6
I think the answer would be 36:16 because if you do the area of the first figure (6x6) it equals 36 and the second figure (4x4) it equals 16
Answer:
Step-by-step explanation:
This is an equation for which you need to solve for the value of the missing angle beta.

sin(15) has a decimal answer that you will find on your calculator. Finding that value makes this equation then
cosβ = .2588190451
Now use the 2nd button and then the cos button to find the angle that has a cos of that decimal. When you hit 2nd then cos, you should see this on your screen:
cos⁻¹ (
After that open parenthesis, enter you decimal then hit the enter button to find the angle. You should get 75, which is Choice B.
I think 12 percent but sorry if I got it super wrong
well, what is 9,744/2,280? take that and move the decimal point two places to the right to find the answer.
