f(x,y)=x^2+2y^2 use the gradient vector Þf(5, 1) to find the tangent line to the level curve f(x, y) = 27 at the point (5, 1). answer choices: 1. 10x + 4y = 27 2. 2x + 4y = 27 3. 5x + 2y = 27 4. 10x − 4y = 27 5. 5x − 2y = 27

100. physics - follow up question

so, (3.75)(4) + (.5)(3.75)(49) or 106.875 radians that's not the correct answer, so is it just the second part to find the additional angle? (.5)(3.75)(49) = 91.875 but it too is incorrect, what am I missing?
