Answer: 55. UTA=29 degrees ==> A
57. RQP=113 degrees ==> B
Explanation:
55. ATS=120
UTS=12x+17
UTA=x+18
UTS=ATS+UTA
12x+17=120+x+18
12x+17=x+138
11x+17=138
11x=121
x=11
UTA=x+18
UTA=11+18
UTA=29 degrees ==> A
57. AQP=9x+2
RQA=75
RQP=1+28x
RQP=RQA+AQP
1+28x=75+9x+2
28x+1=77+9x
19x=76
x=4
RQP=1+28(4)
RQP=1+112
RQP=113 degrees ==> B
