Answer:
Option (A)
Step-by-step explanation:
Measure of an angle formed between a chord and a secant is equal to the half of the difference of the intercepted arcs.
m(∠FEC) = ![\frac{1}{2}[m(\text{arc FC})-m(\text{arc})FD]](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%5Bm%28%5Ctext%7Barc%20FC%7D%29-m%28%5Ctext%7Barc%7D%29FD%5D)
(15 + 6x)° = ![\frac{1}{2}[(24x - 6)^{\circ}-(9+7x)^{\circ}]](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%5B%2824x%20-%206%29%5E%7B%5Ccirc%7D-%289%2B7x%29%5E%7B%5Ccirc%7D%5D)
30 + 12x = (24x - 7x) - (6 + 9)
30 + 12x = 17x - 15
17x - 12x = 30 + 15
5x = 45
x = 9
m(∠FED) = (15 + 6x)
= 15 + 6(9)
= 69°
Option (A) will be the correct option.
Answer: Yes.
Step-by-step explanation: Convert it to a decimal. Percent means per 100. So if you have 50% the decimal form is .5 since you divide 50 by 100. 5% would be .05 etc
Answer:
y = x - 7
Step-by-step explanation:
You take each equation and sub in for x and y.
The first equation would look like this:
16 = 2(23) - 30 Then you answer looks like this:
16 = 16 but if you did that for the second set in the column it looks like this:
18 = 2(25) - 30
18 = 50 - 30
18 = 20 which does not equal canceling the first answer.
And the second answer doesn't make sense because if x > y you shouldn't add to x. The same goes for the third answer.
So that leaves only one answer y = x - 7
Hope this helps
