Line t intersects line u as shown below What is the value of x
1 answer:
Answer:
x = 117 degrees
Step-by-step explanation:
Find the diagram attached
From the diagram, the angle at the top left on line t is equal to theta of the top left on line u and is equal to 117 degrees (corresponding angle)
Also the angle angle on the top left on line u will be equal to x (vertically opposite angle)
Hence the value of x = 117 degrees (vertically opposite to each other on line u)

Answer:
Kalino would need to earn at least a 97 on his fifth test.
Step-by-step explanation:
The average is calculated by adding up the amounts earned on each test and dividing by the total number of tests. In this case, the score for the last test is not known, but the expected average of 90 points is, so we can set up an equation to solve for the unknown test value:
'x' represents the score of the fifth test. Using inverse (opposite) operations and doing the same operation to both sides of the equation, we can first multiply both sides by 5:
x 5 = 90 x 5
353 + x = 450, now subtract 353 from both sides: 353 -353 + x = 450 - 353
x = 97
