Answer:
you cannot convert a repeating decimal into a fraction
Step-by-step explanation:
The two angles form a straight line which is equal to 180 degrees. This makes the angles supplemtary.
To find x, add the two angles together to equal 180:
7x + x+20 = 180
Combine like terms:
8x + 20 = 180
Subtract 20 from both sides:
8x = 160
Divide both sides by 8:
X = 20
If u are looking for area just multiply 150 by 400 but if you are finding perimeter just do 150 plus 150 plus 400 plus 400
Well since there is 12 months in a year you would multiply 35 by 12, so the answer is 420
