Answer:
15
Step-by-step explanation:
A complementary angle is a right angle split into two parts. Since 75 is one of the two parts, we subtract it from 90, giving us an answer of 15.
So F(6) means 6 on the x axis then look to see where the graph is on the Y axis,
in this case on x 6 y=4
It would actually be 62.5
In millimeter, that would be 60,000 :)
