A square was enlarged by the scale factor 2 the new square has sides of 12cm find the area of the original

36cm^2

Step-by-step explanation:

Since the square was enlarged by a scale factor 2, sides of the old square = 12/2

= 6

Area of the original quare = L x L

= 6 x 6

= 36cm^2

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
