Answer:
Height of the building = 115.4 ft.
Step-by-step explanation:
Height of building = AB + 46.4 + CD + 30.5
By applying Pythagoras theorem in ΔABP,
(26)² = (10)²+ (AB)²
676 - 100 = AB²
AB² = 576
AB = 24 ft
By applying sine rule in ΔCDE,
cos(60°) = 
CD = CE × 
CD = 
CD = 14.5 ft
Total Height = 24 + 46.4 + 14.5 + 30.5
= 115.4 ft
Solution: We are given:
μ=180,σ=25,n=100
Therefore the standard error of the mean is
The median means the number that is in the middle of the spnumber sequence in least to greatest.
1) number the numbers up. 2,2,3,6,7
2) start by crossing off the last from the greatest. Then you can see that 3 is the median.
The value of x for given polynomial is 8.8.
<h3>What is Polygon?</h3>
The definition of a polygon is given as a closed two-dimensional figure with three or more straight lines.
Here, the length of sides of given Polygon are:
4x, 6x, 12, 18
Perimeter of polygon = 118 units.
We know that,
Perimeter of polygon = Sum of all sides
118 = 4x + 6x + 12 + 18
118 = 10x + 30
118 - 30 = 10x
10x = 88
x = 88/10
x = 8.8
Thus, the value of x for given polygon is 8.8.
