Answer:
360 = x+123+ 90
x = 147
Step-by-step explanation:
The three angles form a circle which is 360 degrees
360 = x+123+ 90
Subtract 123 and 90 from each side
360 -123 - 90 = x
147 = x
Answer:
C I think. Sorry if it's incorrect but I pretty sure it isn't.
Answer:
f(9) = 42
Step-by-step explanation:
f(9) = (-9)*2 + 5*9 +15
= -18 + 45 + 15
= 42
I would divide the 18000 by 13.26 to get the number of hours needed.
18000/13.26~169.7 days with 8 hour shifts.
Since that is a triangle the expression would be b x h / 2. So 12*12 = 144 / 2 = 72. The answer is 72.
