Answer:
what's the question?
Step-by-step explanation:
7 . 3
--- × ------
10. . 6
= 21
--------
60
= 7/20
10) 7(2m+3)
11) 3(3r-1)
12) 2p(5q+4)
we know that
Two angles are supplementary if their sum is equal to
degrees
in this problem we have


so
therefore
<u>the answer is</u>
The two angles are supplementary
That would be the commutative property
