1 clipe..............7/8
x.......................56
7x/8 = 56
7x = 56*8
x = 56*8/7
x = 8*8
x = 64 clipes
1 clipe = 0,03
64 clipes = 0,03*64
64 clipes = 1,92

<h3>
Answer: Choice C</h3>
================================================
Work Shown:
Reference angle = P
Opposite side = QR = 8.5
Adjacent side = QP = 16
tan(angle) = opposite/adjacent
tan(P) = QR/QP
tan(P) = 8.5/16
tan(P) = 0.53125
tan(P) = 0.53
