Answer:
x = 17
Step-by-step explanation:

is a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output.
Equation of a line in standard form is Ax + By = C
A is a pos. integer and B + C are integers
1) multiply all terms in the equation by 2
2y = x - 6
2) subtract 2y from both sides
2y - 2y (cancelled out) = x - 2y - 6
x - 2y - 6 = 0
3) add 6 to both sides
x-2y = 0 +6 (-6 and +6 cancel out)
therefore,
x - 2y = 6
is the equation in standard form
Sin55 = x/26
26sin55 = x
x = 21.298
