(9) Tangents of a circle at A and B intersect each other at C. If CA = AB, ∠ACB = ________

(10) tanθ ∙ tan(90 – θ) = _____________.

(11) M is foot perpendicular from point P(– 5, 3) on Y – axis, then co-ordinates of M are __________.

(12) The length of diagonals of rhombus are 16 cm and 12 cm. Then the length of side of rhombus is __________.

Answer 1

Answer:

11) (0,3)

12) side of rhombus is whole root of sum of squares of half of diagonals. so side is root of (6^2+8^2)
