#5 = 53° #7 = 125° #6 = 55° #2 = 72° #3 = 55° #1 = 53° #4 = 127°
triangle = 180°
alternating interior angles are the same (#6 & #3 and #5 and #1)
#3 and #7 should equal 180°
#1 and #4 should also equal 180°
#6 and #7 should equal 180°
#4 and #5 should equal 180°
Answer:
True
Step-by-step explanation:
The pages left = total pages - the pages read

Step-by-step explanation:
Answer:
y = -2/13
Step-by-step explanation:
-5 + 13y = -7
Add 5 to each side
-5+5 + 13y = -7+5
13y = -2
Divide by 13
13y/13 = -2/13
y = -2/13
