Can someone help me with this please

20

Step-by-step explanation:

1/3 + 1/5 + 3/10 = 10/30 + 6/30 + 9/30 = 25/30 = 5/6

6/6 - 5/6 = 1/6

1/6 OF 120   of = x    therefore 1/6 x 120 / 1 = 120/6 = 20

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°

hope this
