Step-by-step explanation:

i)70+75= ∠x (EXTERIOR SUM PROPERTY))

:145=∠x

ii) ∠1=50 (THEOREM:- ANGLES OPP. TO EQUAL SIDES OF AN ISOSCELES  

                TRIANGLE  ARE EQUAL.)      

   :50+50=∠x  (EXTERIOR SUM PROPERTY)

   ∴100= ∠x        

iv)  Let an ∠1

     ∠1+100=180 (Linear Pair)

     ∠1=180-100

     ∠1=80

 ∠1=∠x+∠x (EXTERIOR SUM PROPERTY, THEOREM:- ANGLES OPP. TO

                   EQUAL SIDES OF AN ISOSCELES TRIANGLE  ARE EQUAL.)

    80=2∠x

    80/2=∠x

     40=∠x

Sorry,I didn't get the third one.
