4b=a (vertically opposite angle)
b=a/4
in line PQ
B+A+75=180
A/4+A=105
5/4A=105
A=84

b=a/4
=84/4
=21

IN LINE RS
2C+A=180
2C+84=180
2C=96
C=48

HOPE YOU UNDERSTAND IF YES THEN PLEASE DO BRAINLIEST

sandipsssr: THANKS A LOT
harjotsingh36: brainliest kar do
sandipsssr: OK LET HER FINISH

4b + 75 + b = 180° ( linear pair )
5b = 180 - 75
5b = 105
b = 21°

a = 4b ( vertically opposite angles )
a = 21* 4
a = 84°

a + 2c = 180° ( linear pair )
84 + 2c = 180°
180 - 84 = 2c
96 = 2c
c = 48°
84+
