Given, ABCD is an isosceles trapezium. AB || CD AB = 20 cm CD = 10 cm Length of each leg of trapezium = 13 cm By the formula, the area of trapezium is: Area of trapezium = (a+b)h/2 where…
B. QP > QS According to the given condition, ∠QPS=∠RPS By external angle theorem, ∠PSQ=∠RPS+∠PRS ⇒∠PSQ=∠QPS+∠PRS ⇒∠PSQ>∠QPS In a triangle, the side opposite to the greater angle …
Solution: Given y’ – y tan x = 2x sec x (dy/dx) – y tan x = 2x sec x Divide both sides by sec x => (dy/dx) cos x – y sin x = 2x (d/dx)(y cos x) = 2x Integrating both sides We get y cos…
