C=180-D
C=53
B=180-(53+75)
B=180-128
B=52 degrees

You can use a number line to to solve this problem by moving the places
Answer: Absolute Value
Step-by-step explanation:
The | | is a symbol for absolute value. This signifies that the number inside would be positive. Now, this doesn't mean it will always be a number inside absolute value bars. It can also be expressions.
<u>Examples:</u>
|1|: Even though the number inside is a positive 1, we know that it cannot be negative under any circumstances. The only exception would be if there was a negative sign on the outside of the absolute value.
|-1|: We see that there is a -1 in the absolute value. This means that it is actually a 1, not -1. The absolute value is what makes everything inside positive.
|1-5|: To solve this, we know that 1-5=-4. Without the absolute value, the answer -4 would be correct. In this case, we have absolute value, so the answer is actually 4.
|x+2|: x+2 can easily be negative. This would happen is x was a negative number that is smaller than -2. x+2 can also be positive, but the absolute value guarantees that the ending result must be positive.
Answer:
(Can't tell if it's 3/4 plus -7/8 or you need the answer to both so I'll put both of them) 3/4 is .75 -7/8 is -.875. 3/4 + -7/8 is -1/8 which is -.125
