A ladder is leaning against a wall If the angle is between the ground and the ladder at 60 degrees and the wall is 4m how long is the ladder Give exact values?

If the angle between the ladder and the ground is 60 deg, and you know the angle between the ground and the wall is 90 deg, then you have a 30-60-90 degree triangle, which is a common triangle. You should memorize this one. The commonest sides of this right triangle are 4-5-6, with the longest side being the hypoteneuse, in this case the ladder leaning from the ground to the wall. The wall is 4m high, the base of the ladder would be 5m out from the wall, and the length of the ladder is 6m.

If a 15foot ladder is leaning against a 30foot wallthe bottom of the ladder is 9feet from the wallhow many feet above the ground does the ladder touch the wall?
Use Pythagoras' theorem: 152-92 = 144 and the square root of 144 is 12 Answer: 12 feet
What is the measure of angle A if two boards are leaning against each other at a 50 degree angle towards the ground?
We assume A is the angle between the boards where they meet.A = (180 - 50 - 50) = 80 degrees.
Why do military stack arms?
Because it is neater and tidier then laying them on the ground, piling them in a corner or leaning them against a tree.
A 30 foot ladder leaning against the side of a house makes a 70 degrees 5' angle with the ground how far up the side of the house does the ladder reach?
Round the base angle to 70 degrees and use the sine ratio: 30*sine 70 degrees = 28.19077862 feet Height of ladder from the ground = 28 feet to 2 s.f.

Why did they make the Leaning Tower lean?
It was not intentional. The Leaning Tower of Pisa leans because the ground it was built on wasn't firm enough.
How many doors does the Leaning Tower of Pisa have?
One on the ground floor.
How do you prop a mature tree that is leaning?
To prop a mature tree that is leaning, you should consider the ground under the tree. You can use another support or use a string to prop a mature tree that is leaning.
What is wanted friction?
This presumably refers to friction which we find useful. For instance, if you stand on a ladder which is leaning against a wall, it is friction which stops the ladder from slipping. When you walk, friction between your shoes and the ground enables you to push yourself forwards. If the friction is not big enough, you just slip, as on ice.
