Answer:
46/3
Step-by-step explanation:
lt is given that x lies between 270° and 360° so x belongs to the fourth quadrant.
ln the given solution I have use the property that in fourth quadrant only cos and sec trigonometric ratios are positive and other are negative.
By the use of sec x we can find the cos x by reciprocal of it.
after that we can find sin x and take its value as negative as it is in fourth quadrant.
