Answer:

Before solving the given trigonometric relation change everything to sines and cosines

Step-by-step explanation:

consider the given equation;

1/sin(2x+9)=1/cos(3x+26)

Multiplying the above equation on both sides by cos(3x+26)sin(2x+9) then we get,

cos(3x+26)=sin(2x+9)

By using identity,cos a=sin(90-a) expand above equation we will get,

sin(90-(3x+26))=sin(2x+9)

Then,

90-3x+26=2x+9

x=11

So the required value of the angle is 11 degree.

How many solutions exist for the given equation?
sladkih [1.3K]

Answer:

Infinitely many

Step-by-step explanation:

12x + 1 = 3(4x + 1) - 2

12x + 1 = 12x + 3 - 2

12x + 1 = 12x + 1

Both sides are equal for all x, so infinite solutions
