The length of the ladder placed against a vertical wall is twice the distance between the foot of the ladder and the wall. Assertion(A): The angle that the ladder makes with the wall is 60°. Reason(R): If ladder makes angle θ with the wall then sin θ = . 1. A is true, R is false. 2. A is false, R is true. 3. Both A and R are true and R is correct reason for A. 4. Both A and R are true and R is incorrect reason for A.
