Answer:
D
Step-by-step explanation:
solution:
we know that ,
u.v = ΙuΙ ΙvΙcosθ
here,
θ =60° (since the given triangle is equilateral triangle)
u.v = ΙuΙ ΙvΙcos60°
= 1 x 1 x 1/2
u.v = 1/2
now, u.w = ΙuΙ ΙwΙcosθ
= ΙuΙ x cos(60x2)
u.w = -1/2
11764
199,988 ÷17 = 11764
7= 1
8= decimal : 0.00390625
try using symbolab.com
p ≤ 85 or p ≥ 125
i dont know the answer hihihihi
