0.0009208 you can round it to 0.0009 if you want.
Step-by-step explanation:
f=1/g
4=1/-6
=-24
find f
f=1/-6
115 degrees because there are 180 degrees in a triangle so let the missing angle in the trinagle be x. Then we have x+75+40=180. Solving for x and subtracting that from 180 (supplementary angles) we get 115 degrees.
