4. a) since we know RT and TS are the same, we know that triangle RTS is an isosceles triangle, meaning angle RST is the same as TRS; being 32o

    b) angle RTS is --> 180 - 32 - 32 = 116o

    c) we know angle SPQ is 45o, and now that we know angle QSP or RST is 32o, we can find angle PQS. 
        180 - 45 - 32 = 103o

 

5. a) angle DBC 72o because of corresponding angles

    b) angle C is the same as angle DBC because it's an isosceles triangle. (72o)

    c) angle CDB is 180 - 72 - 72 = 36o

    d) angle DEB  is 180 - 90 - 36 = 54o

    e) angle BEA is 36o, and we know that because of alternate angles (equal to angle DBE)

    f) angle EBA is 180 - 36 - 72 = 72o 

 

tell me if I did anything wrong :)
