So after 100 its 105,112,119...........994 x=7(multiples of what we're finding), y=105(where we start from after 100), a multiplied by z=994 we have to find z
step 1 if ∡YWZ=17° then ∡XWZ=17°*2-----> 34°----> because triangle XWY and triangle YWZ are congruents
step 2 ∡WXY=∡WZY-------> because triangle XWY and triangle YWZ are congruents we know that <span>the sum of the internal angles of a triangle is 180 degrees </span>so 180°=∡XWZ+2*∡WXY---------> ∡WXY=[180-∡XWZ]/2 ∡WXY=[180-34°]/2-------> ∡WXY=73°
First we have to assume that each quarter touched each other. Hence the area of the table not covered by the coins (A) is equal to the total area of the table (At) minus the total area of the coins (Ac). Coins are circle, so and r =24.26mm. The area of one coin is then 1848.98mm^2. Hence the equation is A = At - xAc where x is the number of coins.
