Answer:
B
Step-by-step explanation:
Yes it is, due to the fact that you can see exactly what you are subtracting because they are directing above and below each other. In all forms of math we subtract this way for a better understanding of what's needed to be subtracted.
Answer:
The angles are complementary
x is 55 degrees
Step-by-step explanation:
Complementary angles are angles that sums up to 90 degrees
Since a ray intersects two other rays forming a right angle, hence the sum of the two angles is 90degrees and this shows that the angles are complementary.
Given the two angles to be x and (x-20). Taking their sum and equating it to 90 degrees, we will have;
x + x - 20 = 90
2x - 20 = 90
2x = 90+20
2x = 110
x = 110/2
x = 55 degrees
Hence the value of x is 55degrees
