A steel plate has the form of a quarter of a circle with a radius of 49 cm. Two 2-cm holes are to be drilled in the plate. Let (X1,Y1) and (X2,Y2) be the coordinates of the centers of the holes. Find the coordinates for both holes.

    We could assume the holes are drilled at equal distance r from the bottom-left corner. If so, \((x_1, y_1)\) and \((x_2, y_2)\) both would have to satisfy the equation x²+y²=r². We could also assume certain angles at which they are to be drilled. I think we have too little information...

    in polar form we represent a point as (rcos a, r sin a) where r is the radius and a is the angle so (x1,y1) = (34 cos 25 ,34 sin 25) ans (x2,y2) = (34 cos (25+24) , 34 sin (25+24)) =(34 cos49,34sin 49)
