Answer:

B. \overline A \overline C \cong \overline B \overline D

Step-by-step explanation:

The hypotenuse leg theorem (HL) requires the proof that the hypotenuse and the corresponding leg of the triangles to be equal in length. From the diagram, it can be found that \overline D \overline C is a common (shared) side of both triangles, so the additional fact needed is for the hypotenuses to be the same length.

∴ \overline A \overline C \cong \overline B \overline D is the additional fact needed to prove \triangle ADC \cong \triangle BCD

Hope this helps :)

If f(2) = 22 – 5, then what is the value of f(2) + f(5)?
jasenka [17]

Answer:

67

Step-by-step explanation:

With the information of f(2) = 22-5,  you can assume the equation will be f(x) = 11x-5. Using this, you can calculate f(5) by doing 11(5)-5, which is 50. 22-5 is 17, so 50+17=67

Yasmin bought several items at the discount store. She paid 8.75 percent
Y_Kistochka [10]

The total amount of her purchase before tax was added is; $52.46

<h3>How to calculate discounted amount?</h3>

We are told that the percentage sales tax she paid on her purchase was 8.75% which translated to an amount of $4.59.

Now, let the amount of her purchase be x. Thus;

8.75% * x = $4.59

x = 4.59 * 100/8.75

x ≈ $52.46
