Answer:
c
Step-by-step explanation:
How to remember which is which? Well, alphabetically they are:
Complementary add to 90°
Supplementary add to 180°
You can also think:
"C" of Complementary is for "Corner" right angle(a Right Angle), and
"S" of Supplementary is for "Straight" (180° is a straight line)
Or you can think:
when you are right you get a compliment (sounds like complement)
"supplement" (like a vitamin supplement) is something extra, so is bigger
Answer: x = 37 and y = 11
Explanation:
Let x be the bigger number
Let y be the smaller number
x + y = 48
But x is 7 less 4 times the smaller number.
=> x = 4y - 7
Substitute this value of x:
4y - 7 + y = 48
5y = 48 + 7
5y = 55
y = 11
Substitute the value of y in to the equation:
x + 11 = 48
x = 48 - 11
x = 37
Therefore, x = 37 and y = 11
