Question

find the largest angle of $\triangle vwx$. assume that $b$ is a positive number.

Explanation:

Step1: Identify side lengths

The sides of $\triangle VWX$ are: $VW=35b$, $VX=31b$, $WX=33b$

Step2: Locate longest side

Compare lengths: $35b > 33b > 31b$. Longest side is $VW=35b$.

Step3: Match to opposite angle

In a triangle, the largest angle is opposite the longest side. The side $VW$ is opposite $\angle X$.

Answer:

$\angle X$
