Which of the following angles can be added together to create 177°? Explain your answer using words.

Answers

First you’d look for ones units that add up to 7, so in this case (5)4 and (6)3

Add 54 and 63 to get 117

Subtract 117 from 177 to get 60

25 and 35 equal 60 (I just know that from common knowledge I have no idea how to explain that in words)

So 25 + 35 + 54 + 63 = 177

Step-by-step explanation:

Supplementary means 2 angles adding up to 180 or the line of AEF in this case

so supplementary pairs like DEH and HEF would add up to 180, same with DEJ and JEF

Answer:

Angle DEH and angle HEJ and HEK and KEF add up to 180 degrees

Step-by-step explanation:

Two angles are called complementary if their measures add to 90 degrees, and called supplementary if their measures add to 180 degrees. ... For example, a 50-degree angle and a 40-degree angle are complementary; a 60-degree angle and a 120-degree angle are supplementary.

Store A sells boxes of rice for $2.50 each.

Store B sells rice by the pound for $2.50 per pound.

The cost of an amount of rice at either store can be modeled by the function c(n) = 2.5n, where n is the number of boxes for Store A and n is the number of pounds of rice for Store B.

The domain of c(n) = 2.5n is all the real numbers.

For each store, drag the restriction needed on values of n for c(n) to model each situation.
