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 appropriate method to use in solving the given question is permutation. Then, the numbers of ways to arrange the buttons is 1320 ways.
In the given question, the order of arrangement is important, so that the number of ways that Fiona could order the buttons can be determined by permutation method.
i.e 
= 
Red 6
Green 3
Yellow 3
Total 12
Since no two neighbouring buttons of the same colour is allowed, then 3 buttons would be arranged at a time.
Thus, n = 12 and r = 3;

= 
= 
= 
= 12 x 11 x 10

= 1320
Therefore the buttons can be arranged in 1320 ways without two neighbors having the same colour.

Answer:20.16
Step-by-step explanation:
You're going to want to take the total, which is $353.00 and subtract the initial cost, which is $84.00, the number now should be $269. Using that total divide it by $68.00, there you should find your answer of about 4 hours. The precise answer is 3.99588235. But you would round that to 4 hours.
