اختي هلق اذا نزلنا من الزاوية الثانية خط منحسن نلاقي مستطيل ونحيب مساحته ويلي هية ١٢ متر مربع
بعدين منطلع الضلعين الموجودين يلي لح يكونو نفس القيمة 
يعني هوو كمان مستطيل ١٤×٤=٥٦
٥٦+١٢=٦٨ 
يعني الجواب ٦٨ متر مربع ان شاء الله يكون صح لاني حليته نظرياً
 
        
                    
             
        
        
        
Answer:
? = 4.29
Step-by-step explanation:
Remark
Let  x be the question mark. You get the proportionality by using the dimensions of the little triangle to the dimensions of the large triangle.
Equation
14/(14+ 4) = 15/(x + 15)                   Combine like terms on the left
14/18 = 15/(x + 15)                          Cross multiply
14*(x + 15) = 18 * 15                        Simplify the right
14(x + 15) = 270                             Divide by 14
x + 15 = 270 / 14
x + 15 = 19.29                               Subtract 15 from both sides
x = 19.29 - 15
x = 4.29     
 
        
             
        
        
        
1 quart = 31.9995 fluid ounces
5 quarts = 159.997 fluid ounces.
        
             
        
        
        
To get your answer you need to get the average the plane goes and then multiply it by 35 hours. hope this helps:)
 
        
             
        
        
        
The height of the tunnel 5 feet from the edge is 13.82 feet option second 13.82 feet is correct.
<h3>What is an ellipse?</h3>
An ellipse is a locus of a point that moves in a plane such that the sum of its distances from the two points called focus adds up to a constant. It is taken from the cone by cutting it at an angle.
We have:
A tunnel is constructed with a semi-elliptical arch. The width of the tunnel is 60 feet, and the maximum height at the center of the tunnel is 25 feet.
2a = 60 (width of the tunnel is 60 feet)
a = 30
And the maximum height at the center of the tunnel is 25 feet
b = 25 
Let's assume the center of the ellipse is at the origin.
So the equation of the ellipse:

Now plug x = a - 5 = 30 - 5 = 25

After solving:


y = ±13.819 ≈ ±13.82
Height cannot be negative
y = 13.82 feet
Thus, the height of the tunnel 5 feet from the edge is 13.82 feet option second 13.82 feet is correct.
