Hello all! I'm studying for a math cumulative on tuesday, and I've come across these problems that I cant solve.
How do I solve this between 0 inclusive and 2 pi?

sin(x +1) = cos x
Logan has a garden in the shape of a sector of a circle; outer rim of garden is 25 ft long and central along of sector is 50, she wants to add a 3 ft wide walk to the outer rim, how many sq ft of paving does she need to build it?
