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
Answer:
The added both 8x+2x when they were suppose to subtract 8x-2x
Step-by-step explanation:
8x+22= 2x+42
6x= 42-22
6x= 20
x= 3.3 repeating
The first factor simplifies to 1 and the second factor simplifies to 191, which are very easy to evaluate. Hence,
96^2 - 95^2 = (96-95)(96+95)
= (1)(191)
= 191
the answer is 191 :)
