Question

Solve for x. Write the reasons next to each step.Submit603x+10

Answer 1

According to the picture, the proportion that exists between the sides of the triangles is:

`\begin{gathered} (3x+10)/(60)=(1)/(2) \\ \end{gathered}`

From this proportion, clear x:

`\begin{gathered} (3x+10)/(60)=(1)/(2) \\ 3x+10=(60)/(2) \\ 3x=30-10 \\ x=(20)/(3) \end{gathered}`

x has a value of 20/3
