Question

1.4.41 A Use the diagram to the right. B If AD = 18 and AC = 4y - 48, find the value of y. Then find AC and DC What is the value of y? (Type an integer or a decimal.)

Answer 1

Step-by-step explanation:

-We must first find the value of x in the given equation for AC=4y-48.

-After obtaining the value we must add the value of AD = 18

The exercise is as follows:

`\begin{gathered} 4y-48 \\ 4y=48 \\ y=(48)/(4) \\ y=(24)/(2) \\ y=12 \end{gathered}`

Now we must replace the value in the equation; is as follows:

`\begin{gathered} 4y-48 \\ 4(12)-48 \\ 40-48 \\ -8 \end{gathered}`
