Question

triangle congruence: sss and hl. which value of x would make △suv ≅ △tuw by hl? 3 5 2 4

Explanation:

Step1: Recall HL - Hypotenuse - Leg theorem

For right - triangles $\triangle SUV$ and $\triangle TUW$, if $\triangle SUV\cong\triangle TUW$ by HL, then the hypotenuses are equal. So, $2x + 9=4x - 1$.

Step2: Solve the equation for $x$

Subtract $2x$ from both sides: $2x+9 - 2x=4x - 1-2x$, which simplifies to $9 = 2x-1$.

Step3: Isolate $x$

Add 1 to both sides: $9 + 1=2x-1 + 1$, getting $10 = 2x$. Then divide both sides by 2: $\frac{10}{2}=\frac{2x}{2}$, so $x = 5$.

Answer:

5
