Question

Choose all that are correct.
A 10 foot high flag pole makes a shadow of approximately 6.2 feet on a sidewalk. The angle of elevation
of the sun is 58°
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,
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.

Answer 1

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 = $tan^{-1}$ 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
