Answer:
4
Step-by-step explanation:
Maybe you want the value of 16/f when f=4. Put the value of f where f is and do the arithmetic.

You can use a number line to add and subtract
The angles of a triangle add up to 180 degrees
180 - 80 = 100
Both of the unknown angles are the same. So...
100/2= 50
X = 50 degrees
