If 8=10 and 1=7, which describes all the lines that must be parallel?

Lines r and s and lines t and u must be parallel.

Step-by-step explanation:

If which are alternate interior angle corresponding to line t and u.

then by Alternate interior angle property :

Lines t and u must be parallel.

If which are alternate exterior angle corresponding to line r and us.

then by Alternate exterior angle property :

Lines r and s must be parallel.

Hence, Lines r and s and lines t and u must be parallel.

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine

the answer is d. (1.2, -4.7) on edgn

hope this !
