Write an equation for the translation of the function. y = cos x; translated 6 units up A. y = cos x- ­ 6 B. y = cos(x + 6) C. y = cos x + 6 D. y = cos(x ­ 6) I think its B or c..

In triangle ABC, <c is a right angle. Find the remaining sides and angles. Round your answers to the nearest tenth. Show your work. a = 3, c = 19 c^2= a^2+b^2 19^2 = 3^2+b^2 361= 9+b^2 b= √352 = 18.8 what should I do for the next steps?
