Geometry Level 3

s e c x + c o s y + t a n z = 0.87 secx + cosy + tanz = 0.87

c o s x + c o s y + c o s z = 0.56 cosx + cosy + cos z = 0.56

s e c x = 0.87 secx = 0.87

Find the no. of solutions of the above system of equations.


The answer is 0.

s e c x secx doesn't have any values between − 1 -1 and 1 1 , so there is no such value for x x that satisfies s e c x = 0.87 secx = 0.87
