Step-by-step explanation:
the bottom one on the right
Answer:
Two angles are said to be supplementary if they add up to 180 degrees. So the supplement of an angle is obtained by subtracting it from 180. i.e., if x is an angle, its supplement is 180−x
<u>Answer:</u>
<u>Step-by-step explanation:</u>
The sum of interior angles of a quadrilateral is 360°.
If we consider the measure of one of the unknown angles to be
°, we can set up the following equation:

Now we can solve for
:
⇒ 
⇒
[subtracting 192° from both sides]
⇒ 
⇒
[dividing both sides by 2]
⇒ 
Therefore, the other two angles each have a measure of 84°.
The correct answer is the last one.
Hope this helps :)

B
Step-by-step explanation:
its a number line, start at 3, move back -4, end at -1. the arrow above the line shows that its moving backwards/subtraction
