The triangle in the image you've uploaded has labeled sides and a few algebraic expressions, such as $3x + 3$ and $4x + 10$, and angles or points labeled $S$, $R$, $T$, $B$, and $C$.

To answer the questions posed in the image, I will first extract the relevant information and solve for the unknowns.

Known information:

• $CR = 3x + 3$
• $RT = 4x + 10$
• You need to find:
  1. $x$
  2. $CB$
  3. $ST$

Let's proceed step-by-step.

1. Solve for $x$:
   • If the problem suggests that $CR + RT = ST$, we can set up the equation: $3x + 3 + 4x + 10 = ST$ Since we don't have an explicit value for $ST$ yet, I'll assume it's the sum of the two given expressions for now.

I'll start by calculating $x$.It seems that I initially misunderstood how the triangle's dimensions are set up, as no direct equation was formed from the information provided. Let's try a different approach.

It looks like we need additional information, possibly a relationship between sides (such as $CR + RT = ST$, or using a known length for $ST$). Could you confirm if there's any more information given about $ST$ or the triangle's properties, like angle measures or the type of triangle?

Alternatively, if you have specific values for $ST$ or any additional relationships between the sides, that would help determine the value of $x$. Let me know, and we can proceed accordingly!
