Step-by-step explanation:
If t represents the number of tents made, then 4.5t represents the amount of canvas needed. We have ...

Answer:

Step-by-step explanation:
Use the formula
to find the sum of the angles in a polygon, given <em>n</em> sides. This formula tells us the angles of this pentagon must add to 540 (
).
So, we can setup an equation:

Solve for z:
Combine like terms
Subtract 200
Divide by 5
Therefore, the value of z = 68.
40.2 - 13.7 = 26.5
26.5 / 13.7 * 100 = 193.43
answer
193%
