The sum of AB and BC is 180 degrees. So 13x - 10 = 180. 13x = 190.
x = 190/13
Slope= (y2-y1)/(x2-X1)
1=(9-3)/(3-x)
1=6/(3-x)
3-x=6
X=9
If you are trying to make B the subject, you have to divide both sides by 'h' because we need to get rid if 'h' to get 'b' on it's own, and you do the opposite of times - which is to divide. Once you divide both sides by h, you should end up with this:
A/h=b
