Focus on triangles DFC and DFE:
- They are both right triangles because DF is perpendicular to EC
- DC=DE
- DF is a common side
So, the two triangles are congruent. It follows that CF=FE, and in particular

And since x=3, the length of EF is

0 solutions
move the x to one side, and the numbers to the other.
12x (-12x) + 32 (-32)= 12 (-12x) - 7 (-32)
12x - 12x = -7 - 32
0 = -39
0 ≠ -39
∴ you have 0 solutions

Answer:
96 inches
Step-by-step explanation:
We can write a proportion to solve
60 inches x inches
--------------- = -------------
5 ft 8 ft
Using cross products
60 *8 = 5x
480 = 5x
Divide by 5
480/5 = 5x/5
96 = x
96 inches
The answer is 926 :)))
