34 is Y=56 that why he stay with 101 at the end.
Jeff is correct because:
2 sides of a triangle must always be longer than the other side, so:
12+8>19
19+8>12
12+19>8
Since all of them are true, Jeff is correct
Answer:
x = 75°
Step-by-step explanation:
Sum of the interior angles of a triangle = 180°
Therefore,
78° + 27° + x° = 180°
Add like terms
105 + x = 180
105 + x - 105 = 180 - 105 (substraction property of equality)
x = 75°
