The intensity of illumination at any point from a light source is proportional to the square of the reciprocal of the distance between the point and the light source. two lights, one having an intensity eight times that of the other, are 6 m apart. how far from the stronger light is the total illumination least?

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
