Simplify the expression. –16 • 1/8 • 4 + 32 ÷ 2
a. –36
b. 24
c. 8
d. 12

AC=18

Step-by-step explanation:

To find AC, use the Pythagorean Theorem.  Since the longest side (hypotenuse) is known, instead of a²+b²=c², the equation will be c²-a²=b².  12²-8²=b²

144-64=b²

80=b²

√80=√b²

8.94427191=b

That is for one of the two right triangles that make up the tent.  Since there are 2 triangles, 8.94427191 only equals BC or AB.  So, multiply 8.94427191×2=17.88854382 to find the length of AC.

AC= 18
