60+55+x+20 = 180
x + 135 = 180
x = 180 - 135
x = 45

Answer:
x = 14°
y = 5°
Step-by-step explanation:
Angle COL is complementary to both 25° (∠AOC) and 5y (∠LOM). Then it must be true that ...
5y = 25°
y = 5° . . . . . . divide by 5
__
Similarly, angle MOB is complementary to angle LOM, so ...
90° -25° = 3x +23°
42° = 3x . . . . . subtract 23° and simplify
14° = x . . . . . . divide by 3
The values of x and y are ...
3
In a parallelogram, the diagonals (the lines inside from corner to corner) bisect each other. That means the two halves of the diagonal are equal to each other.
So
-9-6x=x-30
-9-6x+6x=x-30+6x
-9=7x-30
21=7x
x=3
1/2 = 12/24
7/8 = 21/24
19/24 = 19/24
6/8 = 18/24
The only answer that is less than 15/24 is 12/24 which is equal to 1/2
