Answer:
Step-by-step explanation:
Measure of inner angle of the n-sided polygon is
~~~~~~~~~~~~~~
m∠PQR = = 144°
PQ = QR ⇒ m∠QPR = m∠QRP
<em>m∠PRQ =</em> ( 180° - 144° ) ÷ 2 = <em>18 </em>°
You want to add 12 and 143 witch would be 155 and then you want to subtract that from 71 and that will give you D
The <em>additional information</em> needed to prove that both triangles are congruent by the SSS Congruence Theorem would be: <em>C. HJ ≅ LN</em>
<em>Recall:</em>
- Based on the Side-Side-Side Congruence Theorem, (SSS), two triangles can be said to be congruent to each other if they have three pairs of congruent sides.
Thus, in the two triangles given, the two triangles has:
- Two pairs of congruent sides - HI ≅ ML and IJ ≅ MN
Therefore, an <em>additional information</em> needed to prove that both triangles are congruent by the SSS Congruence Theorem would be: <em>C. HJ ≅ LN</em>
