If f(x) = x + 8 and g(x) = –4x – 3, find (f + g)(x).
a. (f + g)(x) = 5x + 11
b. (f + g)(x) = –3x + 5
c. (f + g)(x) = –5x – 11
d. (f + g)(x) = 3x – 5

75

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
