Answer:
Yes, 4 + -4 = 0.
Think of it like a number line: The number four is 4 units to the right of the center which is 0, and the number negative four is 4 units to the left of the center. When you add them together, those distances cancel out, and you just get 0.
Answer:
The adjacent angles are: 72 and 108
Step-by-step explanation:
Given
Angle Ratio = 3 : 2
Required
Find the measure of each angle
Let the angles be 
Such that:
--- adjacent angles of a parallelogram
and
--- given
Convert to fraction

Cross Multiply:

Make x the subject:

becomes

Take LCM





Recall that:




<em>Hence, the adjacent angles are: 72 and 108</em>
