tanc=opposite/adjacent=24/7
Answer:
Triangle C
Step-by-step explanation:
Triangle A: All sides have length 9 cm.
<em>By </em><em>SSS</em><em> this is a </em><em>unique</em><em> triangle.
</em>
Triangle B: Two sides have length 10 cm, and the included angle measures 60°.
<em>By </em><em>SAS</em><em> this is a </em><em>unique</em><em> triangle.
</em>
Triangle C: Two angles measure 50°.
<em>This gives us at most </em><em>SS Similarity</em><em>, so we do not have a unique triangle. The triangle sides can be any length. </em><em>This is not unique</em><em>.
</em>
<em>
</em>
Triangle D: Base has length 8 cm, and base angles measure 45°. Which triangle is not a unique triangle?
<em>
This gives us </em><em>ASA</em><em>, so we have a </em><em>unique</em><em> triangle.
</em>
