University · ●○○○○ 10 pts

Find the angle between the lines L1:x=−1+3t, y=1+4t, z=−2tL_1: x=-1+3t,\ y=1+4t,\ z=-2t and L2:x=−1+2s, y=3s, z=−7+sL_2: x=-1+2s,\ y=3s,\ z=-7+s, taken as the angle between their direction vectors ⟨3,4,−2⟩\langle 3,4,-2\rangle and ⟨2,3,1⟩\langle 2,3,1\rangle. Give the angle in degrees. Round to one decimal place.
