Answer:
-2
Step-by-step explanation:
We can find the slope of a line by using two points
(-2,1) and (2,-7)
The slope is given by
m = (y2-y1)/(x2-x1)
= (-7-1)/(2- -2)
= (-8)/(2+2)
= -8/4
=-2
It is angle FED which is equal to angle DEF
80, 82, 88, 90, 100
Now cross out the numbers starting with 80 and 100 and keep going till you get the middle number which would be 88
