Answer:
Step-by-step explanation:
A ladder 5 meters long leans against a wall. The top of the ladder is 4 meters above the ground. The
ladder makes an approximate angle of 53° with the ground. This will not be correct because in the process of calculating the angle , we have
tanФ = 10/6.2
= 1.6129
Ф = 1.6129
= 58.20
And it was not mentioned in the statement that the angle was approximated.
2. A ladder 5 meters long leans against a wall. The top of the ladder is 4 meters above the ground. The
ladder makes an approximate angle of 53° with the ground. This is correct , because the calculation will give an approximate answer of 53
3. A ladder 6 meters long leans against a building. The ladder makes an angle of 60' with the ground. The
ladder reaches approximately 5.2 meters up the wall. This is also correct because the calculation will give an approximate answer of 5.2
