Answer:
20-gon
Step-by-step explanation:
First we start with the formula to find what the sum of angles will be if we know the number of sides.
S=(n-2)*180 where S is the sum of angles and n is the number of sides.
Normally you'd plug in n to find S, but you can do the opposite too.
3240=(n-2)*180
Let me know if you need help working it from here.
Answer:
w=4
Step-by-step explanation:
2(48)+2(8w)+2(6w)=208
1) Start by Distributing the value outside of the parenthesis:
96+16w+12w=208
2) Combine alike terms:
96+28w=208
3) Subtract 96 from both sides:
28w=112
4)Divide both sides by 28 to isolate w:
w=4
