You are correct. For any polygon, the sum of the exterior angles is 360 degrees. You have the correct equation which leads to the correct answer. Nice work on that.

Given:

$\overline{AB}\cong \overline {CD},\overline{BC}\cong \overline {DA}$

To prove:

$\Delta CDA\cong \Delta ABC$

Proof:

In $\Delta CDA\text{ and } \Delta ABC$ ,

$\overline{AB}\cong \overline {CD}$ because Given

$\overline{BC}\cong \overline {DA}$ because Given

$\overline{AC}\cong \overline {AC}$ because Reflexive property.

Corresponding sides of both triangles are congruent. So,

$\Delta CDA\cong \Delta ABC$ because SSS

Therefore, the required missing values are: Given, $\overline{BC}\cong \overline {DA}$ , Reflexive property , $\Delta CDA\cong \Delta ABC$ , SSS respectively.

What is the solution of this equation 4(x-8)+10=-10

Rom4ik [11]

Start by subtracting 10 from both sides.

This gives us 4x - 32 = -20.

Now add 32 to both sides to get 4x = 12.

Now divide both sides by 3 to get <em>x = 3</em>.
