El vector que resulta al multiplicar el escalar λ= -2 por el vector A( 4 N , 300 ) es: ( 8N , 2100 )
( 8N , 1800 )
( 8N , - 1800 )
( - 8N , 2100 )

rounding to the nearest thousandth would be 452,000

answer: answer is b.

[m < b = 120º]

step-by-step explanation:

180°

step-by-step explanation:

sum of equilateral triangle=180°

< n=60°

< m=120°°[angle supplementary of equilateral angle]

< m+< r+< x=360°(sum of exterior angle of triangle)
