Me with this ! coordinates!

the vertices of a triangle are located at:
a (-4, 0)
b (3, -1)
c (3, 2)
what are the coordinates of the vertices after a 90∘ clockwise rotation about the origin? select the coordinates of the vertices of the image triangle from the list below.

(-2, 3)
(-2, -3)
(-1, -3)
(-1, 3)
(-4, 0)
(2, -3)
(1, 3)
(0, 4)
(0, -4)

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°
