Answer 2

HEY MATE HERE IS UR ANSWER

GIVEN THAT THE ANGLES ARE LINEAR PAIRS WHICH IS THAT THE SUM OF THE ANGLES = 180°

THERE FOR NOW ADDING THE ANGLES WE HAVE

{2a - 30 °} + [b + 60°] = 180°

= 2a + b + 30° = 180

2a + b = 180°

a+ b = 90 ° ------- (1)

AND WE ARE GIVEN THAT a - b = 30 °

now

a = 30° + b

now putting this value in eq. ( 1)

we have

30° + b + b = 90 °

b = 30 °

and

a = 60°
