D) bC=* 2) Fill in the following blanks with respect to the figure in the
Question 1 to prove exterior angle theorem.
(1) We know that the sum of angles in a triangle is 180 degrees. So
a+c= degrees
(ii) b and y form a linear pair. Thus,
degrees.
(ii) From () and (0)
a+=
(iv) Similarly, we can prove that
Hence the exterior angle theorem is proved.
and

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°
