Please give the solution and explanation for this question #8

Q8. Show that the equation has exactly one real voot. 4X + 270 - COSx = 0 tip for Q8 10 The Intermediate Value Theorem Suppose that f is continuous on the closed interval [a, b] and let / be any number between f(a) and f(b), where f(a) # f(b). Then there exists a number c in (a, b) such that f(c) = N. By using Intermediate value Theorem )
