Question

May I please get help with this. I still can’t find the answers to them

Answer 1

Since the figures are similar, we can write the following proportion between corresponding sides:

`(AE)/(PT)=(DC)/(SR)`

Now, using the lengths of each side, we have:

`(2)/(4)=(5)/(x)`

Solving for x:

`\begin{gathered} 2\cdot x=4\cdot5 \\ 2x=20 \\ x=(20)/(2) \\ x=10 \end{gathered}`

Therefore the value of x is 10.
