Given: △koe∼△lsv, ot and sp are angle bisectors prove: ot/te = sp/pv

Step-by-step explanation:

Given: △KOE∼△LSV, OT and SP are angle bisectors that is ∠KOT=∠TOE and ∠LSP=∠PSV.

To Prove:

Proof: Since, OT and SP are angle bisectors that is ∠KOT=∠TOE and ∠LSP=∠PSV, and ∠KOE=∠LSV (given).Therefore, ∠TOE=∠PSV      (1)

Consider  △OTE and △PSV,

∠E =  ∠V (△KOE∼△LSV)

∠TOE=∠PSV(From (1)

Thus, by AA similarity, △OTE is similar to △PSV, therefore using similarity condition,

Hence proved.

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
