Question

If 3 x tan(x – 15) = tan(x + 15), then the value
of xis
(a) 30
(b) 45
(C) 60
(d) 90​

Answer 1

Answer:

value of x is 45

Step-by-step explanation:

3 x tan(x-15) = tan(x + 15)

putting value of x = 45

3 x tan( 45-15) = tan(45+15)

3 x tan 30 = tan 60

3 x 1/√3 = √3

√3 = √3

.: the value of x is 45
