Answer:
The answer is pi/4
Step-by-step explanation:
You substitute each x for "pi/4", you will see that the equation is incorrect, the two values are no longer equal.
x=3
The whole line (DF) equals 9x - 39. So you need to make that equal to 47+3x+10 and work out like so. I hope this helps!
9=9m
Next, what you want to do is divide both sides by m to get the variable.
m=1
8cm = 0.08m
8×10^-2 Because we convert
from cm to m.
