Let c be the closed, piecewise smooth curve formed by traveling in straight lines between the points (0, 0, 0), (2, 0, 8), (3, 2, 12), (1, 2, 4), and back to the origin, in that order. (thus the surface s lying interior to c is contained in the plane z = 4x.) use stokes' theorem to evaluate the following integral. c (z cos(x)) dx + (x2yz) dy + (yz) dz

i think it might be a but you might want a second opinion

step-by-step explanation:

hihi so drawing these 2 triangles is fairly simple. all that's left is finding the height of each one. luckily, we have a side length and an angle, so there is a trig function we can use to solve for the height. the easiest one to use would be tangent, since we have 2/3 things needed to find and the third needed is what we are solving for. tan(73°) * 30 ~= 98.13 and tan(73°) * 35 ~= 114.45
