Are window screens similar figures? Explain

Window screens frames are avaliable in three different sizes 5/16", 3/8" or 7/16", this is an industry standard. ... Also, you should see one or two grooves on the bottom of your window frame. Make sure the size of your tracks or grooves will allow the frame thickness you choose will fit.

yes. we do proportions in probabilities.

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
