Any repeated fraction is written as the number devided by nine(s).
for example
0.1111... =1/9
0.23232323... = 23/99
so the given number= -2 -7/9 = -25/9

If the number of positive signs is even and the number of negative signs is odd then it is negative and vice versa. If the number of positive signs is even and the number of negative signs is even then the answer is odd. If the number of positive and negative signs are odd then the answer is always negative.
Answer:
A. 23.6
Step-by-step explanation:
Let the dotted line be y
<u>Then</u>
- y/x = sin(50°) ⇒ x = y/sin (50°)
and
- 29/y = tan (58°) ⇒ y = 29/tan (58°)
<u>So </u>
- x = 29/tan (58°)/sin (50°) ≈ 23.6
<u>Correct answer is</u> A. 23.6
Hello!
We know that the sum of all angles in a triangle is 180 degrees. This can be represented by the following formula:
(angle 1) + (angle 2) + (angle 3) = 180
Insert all known values and variables of triangle ABC into the formula above:
30 + (80 + y) + y = 180
Simplify and combine like terms:
30 + 80 + y + y = 180
110 + 2y = 180
Now subtract 110 from both sides of the equation:
2y = 70
Divide both sides by 2:
y = 35
We have now proven that Y is equal to 35 degrees. Using the known value of Y, we can find the value of X using the same formula as above. Begin by inserting all known values and variables of triangle BCD:
y + y + x = 180
(35) + (35) + x = 180
Combine like terms:
70 + x = 180
Subtract 70 from both sides of the equation:
x = 110
We have now proven that X is equal to 110 degrees. Therefore, considering the known values of X and Y, the answer to this problem is C.
I hope this helps!
