Answer:
I have solved and shown all working in the attached image, but refer to it and use these formula to cross-check the answers
cot(theta) = 1/ sin(theta)
sin(theta) = opposite/ hypotenuse
Use pythagorean theorem to find the length of the adjacent to solve for cot(theta) which is 1/tan(theta).
These formula are all shown in the attached image, but I'm also typing them here.
