ops, sorry i was just new answering to other mmbers
oke, from :
9x+27=6x+66
(move 6x to left side but change its sign, and same for 27 move to right)
9x-6x = 66-27
3x = 39 (both sides divided by 3)
3x/3 = 39/3
x = 13

from ur figure, a=9x+27 and b=6x+66
|dw:1350413801728:dw|

therefore,
9x+27 = 6x+66

just running algebra process
9x+27 = 6x+66
9x-6x = 66-27
3x = 39
so far, so good ?

3x = 39
divided by 3 for both sides, so
3x/3 = 39/3
x = 13

9x+27 = 6x+66
9x-6x = 66-27
3x = 39
3x = 39
divided by 3 for both sides, so
3x/3 = 39/3
x = 13

9x+27 = 6x+66
9x-6x = 66-27
3x = 39
3x = 39
divided by 3 for both sides, so
3x/3 = 39/3
x = 13
m (RSL) = 9x + 27
m (RSL) = 9(13) + 27 = 144

Ok, i repeat again :)
9x+27 = 6x+66
9x-6x = 66-27
3x = 39 3x = 39
divided by 3 for both sides,
3x/3 = 39/3
so, x = 13.
to find the value of m(RSL)=9x+27
substitute x=13 to right side
so, m(RSL) = 9(13)+27 = 117 + 27 = 144 degrees
