The height of the ramp is 9 meter
<u>Solution:</u>
It is given that a skateboard ramp is 15 meters long and it extends 12 meters from the base of the starting point.
If we look at the sum, closely we understand that the ramp is a right angled triangle.
Which has a base length of 12 metres and a hypotenuse of 15 metres.
We need to find its height.
To do so we can use the Pythagoras theorem
Pythagorean theorem, states that the square of the length of the hypotenuse is equal to the sum of squares of the lengths of other two sides of the right-angled triangle.
By above definition, we get

Since we already know the lengths of the hypotenuse and base we can substitute them in the formula and solve for the height.
Let height of the ramp be denoted by ‘h’

Therefore, the height of the ramp is 9 meter
 
        
             
        
        
        
Well....if the triangle shape stays the same then the angle stays the same even if its enlarged in size. It will stay the same because you didn't change the way the shpae looks like, it is just zoomed in.
Answer: The angle measurements stay the same when the figure is enlarged or reduced
        
             
        
        
        
5+3a = 3-2a 
 So 
 5a = -2 
 a=-2/5=-0.4
        
                    
             
        
        
        
The third choice.
The sides of the photo plus the margins of the border equal x.
        
             
        
        
        
The correct answer is B. 130,099.
Hope this helps!
