Find h(x) and its domain given f(x) and g(x) Let f (x) = 2x + 3 and 8(x) = x2 + 4
1. Find f(g(x))
2. Find g(f(x))

step-by-step explanation:

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
