Which statement is true? all quadrilaterals are parallelograms because they have 4 sides. all trapezoids are parallelograms because they have 1 pair of parallel sides. all squares are parallelograms because they have 2 pairs of parallel sides. all polygons are parallelograms because they have straight lines and closed sides.

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

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2
