Answer:
See the image I posted.
Step-by-step explanation:
[tex]\text{1. }a+35^\text{o}=60^\text{o}\ \ \ [\text{An exterior angle of a triangle is equal to the sum of}\\\text{opposite interior angles.]}\\\text{or, }a=25^\text{o}[/tex]
[tex]\text{2. }a+x=180^\text{o}\ \ \ [\text{Sum of angles in straight line is 180}^o.]\\\text{or, }25^\text{o}+x=180^\text{o}\\\text{or, }x=155^\text{o}[/tex]
