y tan 33 = (y + 855) tan 25
Distribute tan 25 to both terms in parenthesees.
y tan 33 = y tan 25 + 855 tan 25
Subtract y tan 25 from both sides of the equation.
y tan 33 - y tan 25 = 855 tan 25
Factor y out of both terms on the left side.
y( tan 33 - tan 25 ) = 855 tan 25
Divide both sides of the equation by ( tan 33 - tan 25 ) .
y = 855 tan 25 / ( tan 33 - tan 25 )
Divide both sides of the equation by tan 25 to get
y tan33/tan25 = (y+855) now divide both sides by y
tan 33/ tan 25 = ( y+855)/y simplify
tan 33 / tan 25 = 1 +855/y subtract 1
tan 33 /tan 25 - 1 = 855/y re-arrange
y = 855 / (tan 33/tan 25 -1)
y tan 33 = (y + 855) tan 25
Distribute tan 25 to both terms in parenthesees.
y tan 33 = y tan 25 + 855 tan 25
Subtract y tan 25 from both sides of the equation.
y tan 33 - y tan 25 = 855 tan 25
Factor y out of both terms on the left side.
y( tan 33 - tan 25 ) = 855 tan 25
Divide both sides of the equation by ( tan 33 - tan 25 ) .
y = 855 tan 25 / ( tan 33 - tan 25 )
