Answer 1

$\huge\fbox\red{answer}$

We know,

       Sum of all the angles of a triangle is $180^o$ {Angle Sum Property)

$(i) \;45^o+30^o+x=180^o\\75^o+x=180^o\\x=180^o-75^o=\underline{105^o}}$

$(ii)\; 90^o+30^o+x=180^o\\120^o+x=180^o\\x= 180^o-120^o={\underline{60^o}$

(iii) We know,

         An exterior angle of a triangle is equal to the sum of its interior oppposite angles.

So,

$65^o+60^o = x\\125^o=x$
