Step-by-step explanation:
Try that.
Set the equations to equal each other because the angles are equal.
8x - 63 = 4x - 27
+63 on both sides
8x = 4x + 36
-4x on both sides
4x = 36
/4 on both sides
x = 9
Answer:
x = 9
The remainder is how much is left after we divide 45/7.
45/7 = about 6
Now, 7*6 = 42
45-42 = 3
Answer: The remainder is 3
