The angle of elevation of a ladder leaning against a wall is 60º and the foot of the ladder is 4.6 m away from the wall. What is the length of the ladder ?
Let AB is a vertical wall and BC is a ladder <ACB=60 degree , Distance of ladder from wall=AC=4.6 m AC/BC=cos 60 degree=1/2 AC/BC=1/2 BC=2*AC BC=2*4.6 BC=9.2 m Ans is 9.2 m
Two ships are sailing in the sea on the two sides of a lighthouse. The angle of elevation of the top of the lighthouse is observed from the ships are 60° and 30° respectively. If the lighthouse is 144 m high, what is the distance between the two ships?
From a point A on a level ground, the angle of elevation of the top tower is 30º. If the tower is 100 m high, the distance of point A from the foot of the tower is:
In the picture you see a ladder with a length of 4 meters, placed against a wall. The ladder touches the box of 1 by 1 meter, which is standing against the wall.
At what height does the top of the ladder touch the wall?
Triangle ABC has a right angle at B. Let Q be along BC and P be along AB such that AQ bisects angle A and CP bisects angle C. If AQ = 9 and CP = 8√2, what is the length of the hypotenuse AC?
