9. For kite PQRS, find mW

m<W=106

Step-by-step explanation:

18+130=148

360-148=212

212/2=106

You have to find a number taht divides both of those numbers, lets start with the smallest one 36 we know that 36 can be divided by 6 so now lets check if we can divide 84 in 6... Effectively we can now lets see what we got we would end with 14 and 6 those can still be divided so lets see with what we can divide both of those with 2 now we would end with 7 and 3 now we can't divide anymore so here is the tricky part how do you know what is the greatest common factor well you will do this... you will get the first number you divided which was 6 and the second number was 2 so now multiply 6 and 2 to get the greates common factor. The GCF would then be 12... Hope this helped
