Answer» Let AB be the rod making an angleθθwith x - axis, and P(x, y) be a point on it such that AP = 3 cm Now PB = AB - AP is (AB = 12 cm ) ∴∴PB = 12-3 cm = 9cm Draw perpendicular from PQ and PR such thatPQ⊥0YandPR⊥0X Part 2Please like the solution 👍 ✔️

Answer»

Let AB be the rod making an angleθθwith x - axis, and P(x, y) be a point on it such that AP = 3 cm

Now PB = AB - AP is (AB = 12 cm )

∴∴PB = 12-3 cm

= 9cm

Draw perpendicular from PQ and PR such thatPQ⊥0YandPR⊥0X
