A. Each side of the original triangle is
the length of each side of the scale drawing.
B. Each side of the original triangle is 2 times the length of each side of the scale drawing.
C. Each side of the original triangle is the same length as each side of the scale drawing.
D. Each side of the original triangle is 2 inches shorter than the scale drawing.

what is the approximate angle of acb if abc is 25cm and the length of segment bc is 15

step-by-step explanation:

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

but there’s no any figure there!
