Answer:

2/11

Step-by-step explanation:

To turn a repeating decimal to a fraction:

1) Multiply by the number of digits repeating to the power of 10. In this case, there are two digits repeating.

x=0.1818...

100x=18.1818...

2) subtract x

99x=18

3) divide by 99

x=18/99

4) simplify

x=2/11

Could someone help me with this please!

Angles 1, 3, and 4 make up a straight line.
Thus, 3x + 90 + 3x - 6 = 180 (angle sum of straight line)
6x - 6 = 90
6x = 96

x = 16
Now angle 1 becomes 3(16) = 48
Angle 1, 2, and 3 also make up a straight line.
Thus, angle 2 + 48 + 90 = 180
angle 2 + 138 = 180
angle 2, therefore, becomes 42. In essence, (A)
