Answer 2

Answer:

Answer

2x and 3y+11 are linear pair.

(i) x=32o

(i) x=32o2(32)+3y+11=180o

(i) x=32o2(32)+3y+11=180o64+11+3y=180o

(i) x=32o2(32)+3y+11=180o64+11+3y=180o3y=180o−75o

(i) x=32o2(32)+3y+11=180o64+11+3y=180o3y=180o−75oy=60−25

(i) x=32o2(32)+3y+11=180o64+11+3y=180o3y=180o−75oy=60−25y=35o

(ii) y=28o

(ii) y=28o2x+3(28)+11=180o

(ii) y=28o2x+3(28)+11=180o2x=180o−84−11

(ii) y=28o2x+3(28)+11=180o2x=180o−84−112x=180o−95o

(ii) y=28o2x+3(28)+11=180o2x=180o−84−112x=180o−95o2x=85o

(ii) y=28o2x+3(28)+11=180o2x=180o−84−112x=180o−95o2x=85ox=285o.
