Answer:
Step-by-step explanation:
When x is -2, F(x) is undefined.
When x is -1, F(x) is -3.
If we see the third option,
When x is -2, we get the square root of -1, which is undefined.
When x is -1, we get the square root of 0, which is just 0, 0-3 is -3.
102
the angles are alternate so they add up to 180
180-78=102
hope this helps :)
if you need me to explain more just let me know :)
