Complementary triangle angles add up to 90 degrees.
It's easy to remember because the C in complementary is the C in corner, they make a perfect corner.

Supplementary triangle angles add up to 180 degrees.
It's easy to remember because the S is supplementary is the S in straight line, they make a straight line.

Help me plssss <br> its for a math test and im braindead atm
Gwar [14]

Answer:

5/8

Step-by-step explanation:

3/8 + 1/4

To add these fractions, you need a lowest common denominator.  Both 4 and 8 "go into" 8, so the lowest common denominator is 8.

In order to change the denominator 4 to 8, you need to multiply both the numerator and the denominator by 2.  So, 1/4 becomes 2/8.

Now, the problem is 3/8 + 2/8.  

You can add the numerators, because the denominator is the same for each fraction.

3/8 + 2/8 = 5/8
