Answer:
y = -9.3
if they are complementary it is 45 degrees
if they are supplementary it is 90 degrees
Step-by-step explanation:
-12.7 = y -3.4
-12.7 + 3.4 = y -3.4 + 3.4
-9.3 = y
complementary angles equal to 90 degrees
supplementary angles equal to 180 degrees
vertical angles have same degrees
so 90/2= 45
180/2 =90
Answer:
