Now this may or may not be work I’m 99.9 percent sure it’s right but if not sorry
Answer:
-6 -4 3 7
Step-by-step explanation:
This is right because if it goes- it goes lower and if it goes up on + it goes higher.
We know that
Applying the Pythagoras Theorem
c=²=a²+b²
where c is the diagonal of the wall
a=12 ft
b=6 ft
c²=12²+6²-----> c²=144+36-----< c²=180-----> c=√180------> c=6√5 ft
the answer is
<span>the exact length of the brace is 6</span>√5 ft
9/20 because you can divide them in half but you can divide them any further.
