The temperature rose by 47 degrees Fahrenheit, because it first went from -32 to 0, and then from 0 to 15.
Rewrite the percentage as a decimal:
8% = 8/100 = 0.08
Multiply the previous result by 24000:
24000*0.08 = $1920
Cos y = 16 / 17.89 = 0.8944
y = cos^-1 (0.8944) = 26.57°
tan 26.57 = BA / 17.89
BA = 17.89 tan 26.57 = 8.95
tan x = 17.89 / 8.95 = 1.999
x = arctan 1.999 = 63.43
sin x = sin 63.43 = 0.8944
