what is the value of x?

➷ We can use the sine rule to determine this

First calculate the length CB

CB = (6 / sin(90)) x sin(45)

CB = 6

180 - (60 + 90) = 30

Angle BCD equals 30 degrees

Now use the sine rule again to calculate x

x = (6/sin(90) x sin(30)

x = 3

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
