Closed circle is including that number on the number line. Open circle designates that it's not that number.
For example, and open circle on 2 with an arrow right/greater than, the numbers that apply are any number greater than two, but not two. So it can be something like 4 or 2.0001 or 2.01.
A closed circle on two with an arrow to the right/greater than means it CAN be 2 (but it still can be the other numbers as well).

Answer:
m<F=50
Step-by-step explanation:
complementary angles mean that together they equal 90, we need to set up an equation to find x, and then put x into angle F to find its measurement :)
m<C+m<F=90
(2x+10)+(x+35)=90
calculate to find x!
x=15
now we put 15 into (x+35)
15+35=50
hope this helps!! :D
