Number 3 “determine whether the triangles are similar if they are write a similarity statement if not explain what would be sufficient to prove the triangles similar”

Step-by-step explanation:

Given are triangles WSX and TRS

The two lines namely RW and TX intersect at point S thus making two triangles

From the given information we find that

angle TSR = angleWSX(vertically opposite angles)

But this is not sufficient to prove that two triangles are similarl.  Atleast two angles must be congruent

Hence we must have information as angle RST = angle SWX or angle TRS=angleWXS to prove these are similar

Or angle RST =angle SXW or two lines TR||WX to complete the proof

to determine the unit cost your would divide the total cost by the number sold.
