Step-by-step explanation:
There are two way of showing a model for 2×5
Both models give the same solution:
In the attached picture we can show two types of diagram.
Answer:
6.9 foot.
Step-by-step explanation:
Given: Length of lamp post= 12-foot.
The angle of elevation of the sun is 60°.
∴ The length of Lamp post, which is opposite is 12-foot.
Now, finding the length of shadow cast by foot lamp.
Length of shadow is adjacent.
∴ We know the formula for =
Next, putting the value in the formula.
⇒
Cross multiplying both side and using the value of Tan 60°
∴ Adjacent= ≅ 6.9 (nearest tenth value)
6.9 is the length of shadow cast by a 12-foot lamp post.
