Answer:
The fence is 18.9 ft long.
Step-by-step explanation:
If you were to create a diagonal line from corner to corner with a square that is 10x16ft, you would have a triangle with 2 known sides and an unknown value. In this case, because you are making a 90° triangle, you can use Pythagorean Theorem:
a^{2} + b^{2} = c^{2}
- by plugging in the two values given (10 and 16):
10^{2} + 16^{2} = c^{2}
100 + 256 = c^{2}
356 = c^{2}
√356 = c
18.9 = c
5y = -3x + 7
y = -3/5x + 7/5
Parallel = same slope
y = -3/5x + b
3 = -3/5 + b, b = 18/5
Standard form: Ax + By = C
y = -3/5x + 18/5
-3/5x - y = -18/5
Multiply by -5
Solution: 3x + 5y = 18
