Using the ambigous case in triangles, A=38.3ft, b=31.2 ft, angle B=34°54'

i would say b) is your answer

sorry if im wrong

step-by-step explanation:

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)

so mark-up is 0.4 multiplied by 180 = 72
