Question

If tan( 3x + 30 ) =1 then find the value of x PLZZ TELL THAT HOW 45 IS GETED

Answer 1

5 is the best answer

Answer 2

Given :-

tan ( 3x + 30 ) = 1

Solution :-

As tan 45° = 1
so, at the place of 1 we can write as tan 45.

tan ( 3x + 30 ) = 1

tan ( 3x + 30 ) = tan 45

( dividing both side by tan )

( 3x + 30 ) = 45

3x = 45 - 30

3x = 15

x = 5

So,
the value of x is 5 ! !

Q . HOW 45 IS GETED ?

Ans :- since tan 45 = 1
and equation tan ( 3x + 30 ) = 1
also has 1 so, we can replace that 1 by tan 45!!
