The length of AC found using the Pythagorean Theorem is C) 120.
The length of AC can be found using the Pythagorean Theorem. The Pythagorean Theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. In this case, the hypotenuse is AC, and the other two sides are AB and BC.
AB = 60 units
BC = 80 units
Plugging these values into the Pythagorean Theorem, we get:
=
+
=
+
= 3600 + 6400
= 10000
AC = (10000)
AC = 100 * (10)
AC = 120 units
Therefore, the length of AC is C) 120.

Answer:
y=9
Step-by-step explanation:
-2[(4y+1)-(2y-2)]=6(7-y)-6
-2[4y+1-2y-2]=6(7-y)-6
-2[2y-1]=6(7-y)-6
-2y+2=6(7-y)-6
-2y+2=42-6y-6
Add 6y to both sides
4y+2=42-6
4y+2=38
Subtract 2 from both sides
4y=36
Divide both sides by 4
y=9
