step-by-step explanation:

1-16

2-32

4-64

8-128

all multiples of 16

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm
