Answer:
Below in bold.
Step-by-step explanation:
We see from the diagram that:
SY = SK + KY
So, substituting the given values:-
36 - x = 13x - 5 + 2x + 9
-x - 13x - 2x = - 5 + 9 - 36
-16x = -32
x = 32/16 = 2.
So SK = 13(2) - 5 = 21.
KY = 2(2) + 9 = 13.
SY = 36 - 2 = 34.
21 + 13 = 34 so this is a check that our calculation is correct.
