72 1/9
0.1 recurring of the number 1 is 1/9 of the number
13: 72.25
14: 52
For 14, you need to split the figure into a triangle and rectangle.
Answer:
n = - 4
Step-by-step explanation:
n + 8 = 4
n = 4 - 8
n = - 4

In the given figure, the angles 5 and 6 form Vertical opposite angle pair.
so, correct choice is Vertical
4x - 13 = 2x + 9
Add 13 to each side
4x = 2x + 22
Subtract 2x from both sides
2x = 22
Divide both sides by 2
x = 11
