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
Answer:
21mm
Step-by-step explanation:
The formula for solving the area of a rhombus is :
, where x and y are two intersecting diagonals.
In this case, we are given both values, thankfully. 6 and 7 are to be replaced with x & y. Now, the rest you have to do is simple math.

The area of the rhombus is 21mm.
To get the variance, start with finding the mean of your data points:
(23 + 19 + 22 + 30 + 28) / 5 = 24.4
Now take each data point and subtract the mean from it, then square that value:
23 - 24.4 = -1.4 * -1.4 = 1.96
19 - 24.4 = -5.4 * -5.4 = 29.16
22 - 24.4 = -2.4 * -2.4 = 5.76
30 - 24.4 = 5.6 * 5.6 = 31.36
28 - 24.4 = 3.6 * 3.6 = 12.96
Now get the average of those new numbers. That is your variance:
(1.96 + 29.16 + 5.76 + 31.36 + 12.96) / 5 = 16.24
The standard deviation will be the square root of the variance:
√(16.24) = 4.0299 (rounded to 4DP)
