Answer:
The total height of coconut Tree = H + 10ft = 11.77 ft
Step-by-step explanation:
Given as,
The height of Kalei = 6ft
The distance of Kalei from the coconut Tree = 10 feet
Angle of elevation of kalei up to the coconut on tree = 30°
<u>Note : look at the pic attache </u>
From figure it is mention that
Total height of Tree = 6 ft + H
So, Tan 30° =
Tan 30° =
∴ H = 10 Tan 30° = 10 × 0.577 Note : tan 30° = 0.577
i.e H = 5.77 ft
Hence the total height of coconut tree = 6 + 5.77 = 11.77 ft Answer
