Answer:
what is cos and sin ?
Step-by-step explanation:
1035.33156649 meters high is the helicopter flying over the building.
Given that, an observer (O) is located 900 feet from a building (B). The observer notices a helicopter (H) flying at a 49° angle of elevation.
We need to find how high is the helicopter flying over the building.
<h3>How to find the height of the building using trigonometry?</h3>
To measure the heights and distances of different objects, we use trigonometric ratios.
Here, use the Tangent rule to calculate the height of the building.
tan(angle) = opposite/adjacent
Now, tan 49°=h/900
⇒h=1035.33156649 meters
Therefore, 1035.33156649 meters high is the helicopter flying over the building.

#SPJ1
- x intercept=a=3
- y intercept=b=-2
We need the normal form first
Multiply by 6to bring standard form
A = 6.7 :) hope this helps I double checked
-0.85, 0.25, 60, 60 2/40
hope this helps! :)
