Question

Q30. A ladder which is inclined at an angle of 60° to the horizontal reaches a 11 m long wall
at a point 2.35m below the top of the wall. Find the length of the ladder.
(Use V3 = 1.73)

Answer 1

Answer:

is yours question right

Answer 2

Answer:

AC/BC= H/B

cos60 = h/8.65

1/2 = h/ 8.65

2h = 865/100

h = 865/200

h= 4.325m

So length of ladder is 4.325 m
