Answer:
The height of the tower is 94 ft
Step-by-step explanation:
In a given right angle triangle we will use <em>''sohcahtoa"</em><em>.</em>
tan (60°) = opp/adj
tan (60°) = x/50
√3 = x/50
x = 50√3
x = 50 × 1.732
x = 86.6
Now, The height of the tower is (x + 7)
86.6 + 7 = 93.6 ≈ 94
Thus, The height of the tower is 94 ft

Answer:
Perimeter will be = 21.6
Step-by-step explanation:
As we know the formula to get the length between two points A and B having coordinates A(x,y) and B (a,b) is
AB = √(x-a)²+(y-b)²
We will use this formula to get the lengths of all sides of the quadrilateral.
AB=√(4+3)²+(2-2)² =√7² =7
BC = √(3-4)²+(-3-2)²=√(-1)²+(-5)² = √1+25=√26 = 5.1
CD = √(3+3)²+(-3-3)² = √6²+(-6)² = √72 = 8.5
DA = √(-3+3)²+(3-2)² =√1 = 1
Since perimeter of the quadrilateral = sum of lengths of all sides
Perimeter = 7 + 5.1 + 8.5 + 1 = 21.6
