Answer:
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
