Answer:
1) m= 45 and n= 15, 2) m= 44 and n=68, 3) m= 67.5 and n= 56.25
Explanation:
1) 45+90= 135
 180-130= 45
 m=45
 45+45= 90
 90+60= 150
 180-150= 30
 30/2= 15
 n= 15
2) 68+68= 136
 180-136= 44
 m= 44
 180-44= 136
 136/2= 68
 n=68
 68 for each
3) 180-15=165
 165/2= 82.5
 90-15= 75
 75+75= 150
 180-150=30
 30+82.5= 112.5
 180- 112.5= 67.5
 m= 67.5
 180-67.5= 112.5
 112.5/2= 56.25
 n= 56.25
