Step-by-step explanation:
You need to use the Pythagorean theorem:
L = 
= 13,4 feet
Those are adjacent angles. They equal 180 degrees.
10x-20+6x+8= 180
16x-12=180
Add 12.
16x= 192
x=12
I hope this helps!

7. No, the associative property does not work for subtraction or division, they do not hold for the associative property. For example,
2+ (3+4) = (2+3) + 4 2- (3-4) = (2-3) – 4
2+7 = 5+4 2 + 1 = -1-4
9 = 9 3 = -5, which is not true
8. No, the commutative property does not work for subtraction or division, they will give a different result. For example,
5+6 = 6+5 5-6 ≠ 6-5
