Mrylee is a stamp collector and buys commemorative stamps suppose she'd by the combination of 47 cents stamps in 34 cents stamps at the post office if she spends exactly $21.50 on 50 stamps how many of each did she buy​

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

im guessing (23,14). hope this : )

if i knew id you bro,, my bad
