Question

Given that RT | | AC, SR = 10, SC = 4, and CT = 4, find SA

Answer 1

We have the following:

We can calculate this by means of the following proportion

`(SA)/(SR)=(SC)/(ST)`

replacing:

`\begin{gathered} (SA)/(10)=(4)/(4+4) \\ SA=(10\cdot4)/(8) \\ SA=5 \end{gathered}`

Therefore, SA is equal a 5
