Question

If , tan 3x = sin45 cos45 + sin30
Then,find the value of x ( x < 90 )

Answer 1

Step-by-step explanation:

tan 3x = Sin45*Cos45 + Sin30

tan 3x = (1/√2)(1/√2) + 1/2

tan 3x = 1/2 + 1/2

tan 3x = 1

tan 3x = tan 45°

3x = 45°

x = 15°

Answer 2

ANSWER

15

Step-by-step explanation:

tan 3x = sin45 ×cos45 + sin30

= 1/2 +1/2

tan 3x = 1

tan 3x = tan 45

3x = 45

x = 15
