The angle is in the second quadrant so only the sine is positive .
Length of the hypotenuse = sqrt (-1^2 + 3^2) = sqrt10
sine = 1/sqrt10 = 0.3162 to 4 dec places
tangent = 1 / -3 = -0.3333 to 4 d p's
cosine = -3/sqrt10 = -0.9487 to 4 d, p's.
Answer:
those are pretty good! all a's and b's are good! Keep up the good work!!
Step-by-step explanation:
352 divided by 25 = 14.08 so technically 14 r 8
