3 supplementary angles are in the ratio of 6 is to 7 is to 5 find the angle​

90,105,75

Step-by-step explanation:

let the angle be x

so,

6x+7x+5x = 3×90

18x = 270

x= 270/18

x = 15

so the angles are , 6x = 90 , 7x = 105 , 5x = 75

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
