Answer:
AC = 10sin40°
Step-by-step explanation:
Using the sine ratio in the right triangle
sin40° = 
= 
, then
sin40° = 
( multiply both sides by 10 )
10sin40° = AC
Answer:
........................
Step-by-step explanation:
I hope this helps you
3x+y-2x-y= -14+9
x= -5
-2. (-5) -y=9
10-y=9
y=1
To find the mean you add up all the numbers then divide the sum by how many numbers there are :
8+16+12+11+8=55
there are 5 numbers in the equation so you divide 55 by 5 :
55÷5= 11
the mean is 11
hope this helped
If that is a , then another way to write it is 984
