Answer:
F=140
Step-by-step explanation:
Remember that all angles will be able to add to 720 so you should get something like this:
130+120+110+x-20+x-60+x-40=720
Then solve for x to do this:
130+120+110+x-20+x-60+x-40=720
360-120+3x=720
3x+240=720
3x=480
x=480/3
x=160
With x=160, you can plug in to solve and find that F=140
Answer:
K=-89

Answer:
169.56 ft.
Step-by-step explanation:
The formula for Circumference is simply:
C = π * D
Circumference equals Pi times diameter
Our diameter is 54, because diameter is just Radius times 2.
54 • Pi (first three digits, 3.14) = 169.56
The answer is c which is correct
