Given the picture, what is the length of ac? a) 4.5 b) 5 c) 7.5 d) 8

we know that

triangles BCD and ACE are similar

so, their ratios of sides must be equal

Calculation of y:

we can see that

AC=AB+BC

AC=y+3

CE=CD+DE

CE=4+6

CE=10

now, we can plug values

now, we can solve for y

Calculation of AC:

we know that

AC=y+3

we can plug y

and we get

...................Answer

the answer is b i just did that

step-by-step explanation:

439400

step-by-step explanation:

130^2 = 16900
