Alright soo complementary means the two add up to 90. So number 1 is commentary but 2 is not.
Supplementary means they add to 180. So number 3 is but 4 isn’t.
Hope this helps!

1 is correct for complementary angles and 1 is also correct for supplementary angles. A complementary angle is when two measures of 2 different angles equal 90 same goes for supplementary angles but they have to equal 180

Find the greatest common factor of the following monomials 3B + 30 B
ryzh [129]

Answer:

3B

Step-by-step explanation:

The greatest common factor is the greatest number that will divide two values. We have two values 3B and 30B. Each has numbers which multiply together to give the number. We need to find the highest value or most in common they share. Each has the factors:

3B: 1,3,B

30B: 1, 3, 5, 6, 10, B

Both have 3 and B has factors. Our GCF is these two factors.

What is angle DCE?<br><br> A. 34<br> B. 85<br> C. 102<br> D. 98
s2008m [1.1K]
The red line is 180 degrees. So the arcs on top of the circle all equal up to 180 degrees. the number 72 doesn't really matter cause you're trying to find out the angle of DCE which is on the other side of the circle. So you gotta find the arc length of DE which is 68 because 180-112=68. So to find the angle, you have to divide the opposite arc length by two, which is 34. 

ANSWER: A. 34. you're welcomee!!

Name the property illustrated be each statement. (3x+2)-5=(3x+2)-5
Evgesh-ka [11]
The associative property states that we can add numbers in any way we want to still get the same sum, so the parenthesis here can essentially be tossed out to get 3x+2-5=3x-3. However, make sure, for example, that you don't add x and 1 together in 3(x)+1 as you still have to multiply the x with 3 before adding the 1 according to PEMDAS
