Answer:
A) 50°, 65°, 65°
B) 45°, 50°, 85°
C) 20°, 60°, 100°
Step-by-step explanation:
To see if the angles can be used to construct triangles, you have to check if the degrees add up to 180 (Since the degrees in a triangle always have to add up to 180 degrees).
<u>A) 50° + 65° + 65° = 180° (Good!)</u>
<u>B) 45° + 50° + 85° = 180° (Good!)</u>
<u>C) 20° + 60° + 100° = 180° (Good!)</u>
<em>D) 30° + 60° + 70° = 160° (Bad!)</em>
<em>E) 20° + 45° + 120° = 185° (Bad!)</em>
