Answer:
cos(X+Y) = cos(55+35) = cos(90) = 0
Step-by-step explanation:
cos(X+Y) = cosXcosY - sinXsinY
cos(55+35) = cos(55)cos(35) - sin(55)sin(35)
cos(55+35) = cos(55)cos(35) - cos(90-55)cos(90-35)
cos(55+35) = cos(55)cos(35) - cos(35)cos(55)
cos(55+35) = 0
cos(90) = 0

Step-by-step explanation:</h2>
The function f(x) is given by:

and the function g(x) is given by:

Now, we are asked to find the solution of the equation:

i.e. we have to find the value of x such that both the functions are equal i.e.

Now, on solving the equation using the quadratic formula i.e. the solution of the equation:

is given by:

Here we have:

Hence, the solution is given by:
