Step-by-step explanation:
a) The measure of angle 7 is also 47 degrees. We know this because angle 5 and angle 7 are vertical angles and vertical angles are always equal.
b and c) Since we know that a straight line has an angle of 180 degrees and that the sum of angle 5 and angle 6 will add to this, we can use that to find the value of x like this:

Answer:
_|_____________________|_____________________|_
1/3 <u>2/3</u> 3/3
Step-by-step explanation:
draw a line:
____________________________________________
then divide the line by three's:
_|_____________________|_____________________|_
then mark the first part 1/3
the second 2/3 and third 3/3:
_|_____________________|_____________________|_
1/3 2/3 3/3
<span>It depends what the numbers are. If it is two positive integers then the sum will be positive. But if it is two negative integers then the sum will be negative.
