Answer:
Measure 8 is 135°
Step-by-step explanation:
Measure 1 and Measure 8 are alternate exterior angles.
Sum of internal angles of any polygon is: (n-2)x180
So measure of an interior edge is ( ( n - 2 ) x 180 ) / n = 140
So 140n = 180n - 360
40n = 360
n = 9
So it's a nonagon.
Hope this helps :)
Answer:
B
Step-by-step explanation:
y=-2x+2
y=mx+b
m is slope so.here m is -2
y=-2+10.passes through the point (3,-4)
because -4=-2*3+2
-4=-6+2
-4=-4
Answer:
Y=2x-5
Step-by-step explanation:
Parallel m=2
Y=mx+c
-1=2(2)+c
C=-5
