Answer:
and 
Step-by-step explanation:
We are given that sin x+cos x=cos 2x
We have to solve the given equation for 

Because 








Tan x is positive in I and III quadrant
In III quadrant angle
replace by 
Therefore, 

excuse the writing io used my mouse
so the aim is to find a simple factor thst when u multiply the divisoor by it si lower thatn the dividend
in this case i used 10 so 10*36=360
then u subtract 360 ( 540-360=180)from the dividend and record the ten which i did on right side of the attachment
then u find another factor that can now multiply 36 but be less that 180 i chose 5
5*36=180
180-180= 0
finally u jus add the factors that used which are the 10 and 5= 15
therefore 540/36 =15
I’m doing this too hopefully someone answers quick cause I’m confused also.
