Convert to improper frist
2 and 7/8=16/8+7/8=23/8
2 and 1/4=8/4+1/4=9/4
(23/8)/(9/4)
make bottom 1
times the whole thing by (4/9)/(4/9)
(92/72)/(36/36)=
92/72=
23/18

Thus, the null and the alternative hypothesis can be computed as:
Null hypothesis:

Alternative hypothesis:

A) <DAE = 180-126 = 54
b) <EBC = 90 - 48 = 42
c) <BAE = 180-48-54=78
