8.75 cm²

Step-by-step explanation:

The area (A) of the triangle is calculated as one half the product of the 2 given sides and the sine of the angle between them, that is

A = × MN × MO × sin M

   = 0.5 × 5 × 7 × sin30° = 8.75 cm²

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p
