Answer:
D
Step-by-step explanation:
option d has the largest slope
1- FM is 3
we know that FM and FG are radius of the circle. so:
FM =FG
so if we find FG by Pythagorean theorem, we find FM, too
FL (hypotenuse) is 5
HL is 8. GL is half of HL. so GL is 4
now we can use Pythagorean theorem to find FG

2- x is 40
BAD is half of m DB
ADB is half of m AB
so BAD is 50
and ADB is 90
Then ABD will be:

good luck
The answer you are looking for is associative property of addition.
In associative property, no matter where the parenthesis are, a + (b + c) is going to be equal to (a + b) + c. Since the parenthesis follow the equation a + (b + c) = (a + b) + c, you can assume you are using the associative property. Lastly, add "of addition" to associative property, since you are using addition, not multiplication.
I hope this helps!
