    Sorry that you cried...you need to view this as two triangles, try drawing the two triangles.

    Now since both triangles are "congruent" then side "ST" must be parallel to "RQ"

    St6atement 2: <QRS = <TSP (consider that two angles equal)

    steatement 3: <SPT = <RPQ (once again, consider that two angles equal)

    Okay, not sure about statement 4.."similar" means basic shape is same, but not necessarily congruent.

    60: (60+x) = 48: (48+36) these are proportions

    no, they are proportionate, so they wont equal exactly.

    60/(60+x) = 48/(48+36)

    so 48/84

    84*60=(60+x)48 ?

    48+36 = 84 therefore we have: |dw:1436523838479:dw|

    Since the triangles are simi9lar, corresponding sides have proportional lengths. |dw:1436566575542:dw|

    Don't do any calculations. The question is only asking how to complete setting up the proportion.

    5040 = 2880 - 48x 5040-2880 = 48 x 2160 =48x x=45
