Complete the statements. 1.the solution of 3tan2x − 1 = 0 if x is in the first quadrant is °. 2. the solution of 3tan2x − 1 = 0 if x is in the second quadrant is. 1. a.30 b.60 c.150 d. 240 2. a.30 b.60 c.150 d.240

1. 30

2. 150

Step-by-step explanation:

Lets assume tan(x) = u

Now we solve for 'u'

add 1 on both sides

, divide both sides by 3

Take square root on both sides

We replace tan(x) for 'u'

x = 30 because  in first quadrant

      x = 30      (tan is positive in first quadrant)

  x = 150 because  in second quadrant

     tan is negative in second quadrant

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
