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.
Convert the fraction to a decimal:
1/25 = 0.04
Multiply by 100 to get the percent:
0.04 x 100 = 4%
Answer:
x = - 7
Step-by-step explanation:
Given
3(x - 4) = 5x + 2 ← distribute left side
3x - 12 = 5x + 2 ( subtract 5x from both sides )
- 2x - 12 = 2 ( add 12 to both sides )
- 2x = 14 ( divide both sides by - 2 )
x = - 7
504 because when you multiply 9 by 8 and then by 7 (9x8x7) you get 504.
4 - 8 = -4
A negative number is alwats at the left in a horizontal line.
Let's try to rapresent it.
-4 -3 -2 -1 0 +1 +2 +3 +4
So, you count from +4 to -4
Your answer is "8 units to the left of 4"
