Which polygon has no of sides equal to diagonal?
The formula for the number of diagonals in a polygon is s*(s-1)/2 - s To find such a polygon, we solve for when that formula equals s s*(s-1)/2 - s = s s*(s-1)/2 = 2s (s-1)/2 = 2 s-1 = 4 s = 5 Thus, the polygon with this property is the pentagon.
Formula of radious given curve length and chord length?
R = radius c = chord length s = curve length c = 2Rsin(s/2R) you can solve for radius by trial and error as this is a transcendental equation
What is the equation of the line of symmetry?
7-8=d-s
What is the formula for finding the area of a square?
A=s^2 or A=s*s A is the area, and s is a side.
If the diameter of a rectangle is 10 meters and one side is 2 meters larger than another then what are the lengths of the sides?
In a rectangle there are two sets of lines - those opposite each other are the same length. So the phrasing of this question tells us that the two longest sides are 2 metres longer than the short sides, and that all the sides add up to 10 metres. So, if we call the short sides S, then 2S + 2(S+2) = 10 This works out to 2S + 2S + 4 = 10 This reduces to 4S = 6 And that gives us S = 6/4 So S = 1.5 So now we know that the short sides are both 1.5 metres and the long sides are both 3.5 metres Adding these together we get 1.5 + 1.5 + 3.5 + 3.5 = 10
