2 months.
the equations are
65m+50 and 45m+90
you set them equal together
65m+50=45m+90
and you get 2.
Assuming that c is the length of AB (as is usually the case in the angle-side notation for triangles):
If sin(35) = 12/c, we can transform by multiplying both sides by c, and dividing both by sin(35) to get
c = 12/sin(35)

The expression that does not represent the sum of n and 6 is 6n
h=-3
<em><u>Substitute h in</u> 2-6h</em>
2-6h=
2-6*(-3)=2+18=20
<em>Answer: 20</em>
