Q21.
6x-19=3x+32
6x-3x=32+19
3x=51
x=51/3
x=17
total of all these angles will be 360 so put the value of x in above equations the answer for both sides will be 83
now
83+83=166
360-166=194
194/2=97
m1 is 97
Q22.
20x+11=25x-14
25x-20x=11+14
5x=25
x=25/5
x=5
total of all these angles will be 360 so put the value of x in above equations the answer for both sides will be 111
now
111+111=222
360-222=138
138/2=68
m1 is 69
