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
