3sin60°+xcos30°.tan45°=xcot30°

x = (6)/(4 -3)

Step-by-step explanation:

sin60 degree = /2

cos30 degree = 1/2

tan 45 degree =  sin45 degree / cos45 degree = (/2)/( /2) = 1

cot 30 degree = cos30 / sin30 = ( /2)/(1/2)  =

so, let us plug the above values in the given eqution and solve for x

3( /2 ) + x(1/2) *1 = x()

3( /2 )  = x() -x(1/2)

3( /2 )  = x(()-(1/2)) (by taking x as a common factor)

3( /2 ) = x(((2)-(1))/2))    (making the same common denominator

now devide both sides by (((2)-(1))/2))

x  = 3( /2 )  / (((2)-(1))/2))

x = 3( ) / ((2)-(1))

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option
