Answer» 3y+2x=180( they form a linear pair) replacing value of x we get3y+2(30)=1803y+ 60 =1803y = 180-603y = 120y= 120/3y = 40 answer b 40 x=30° then,2×30=60so,2x=60 now we know that angle made on straigt line is always of 180° so,3y+2x=180° 3y+60=180° 3y=180-60=120 3y=120 y=120÷3=40 so,the value of y =40 |
