Answer:
Step-by-step explanation:
the side with the biggest angel across form it has the longest side
the unknown angle would be 180-50-20=110
so it would go 20,50,110
3 10/11 - -4/5
=3 10/11 + 4/5
=3 50/55 + 44/55
=3 94/55
=4 39/55
108 °
∠DOC = 180° - 112° = 68°
∠DOC = 1/2(arc AB + arc DC)
68 = 1/2(y + 80 + y)
68 = y + 40
y = 28
arc dc = 80 + 28 = 108 °
25, 32, 40 can not form a right angle triangle.
By Pythagoras theorem,
⇒ (40)² = (25)² + (32)²
⇒ 1600 = 625 + 1024
⇒ 1600 ≠ 1689
