Which of the following statements is false? A. The diagonals of a parallelogram bisect each other.
B. The sum of the measures of the angles of a quadrilateral is 180
C. A square is a rectangle.
D. The base angles of an isosceles trapezoid are congruent.

B

Step-by-step explanation:

The sum of the measures of the angles of a quadrilateral is 360, not 180

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°
