It's the arithmetic sequence not geometric sequence.
Answer:
3x³ + x² + x + 1
= 3x³ - 3x² + 4x² - 4x + 5x - 5 + 6
= 3x²(x - 1) + 4x(x - 1) + 5(x - 1) + 6
= (x - 1)(3x² + 4x + 5) + 6
but 3x³ + x² + x + 1 = (x - 1).Q(x) + R
=> Q(x) = 3x² + 4x + 5
R = 6
Answer:
Therefore the correct option is 2. 35 degree.

Step-by-step explanation:
Consider an Isosceles Triangle, Δ ABC where,
∠BAC = 110°
TO Find:
∠ ABC = ∠ACB = ?
Solution:
For an Isosceles Triangle
Base Angles are equal
∴
Now,
Triangle sum property:
In a Triangle sum of the measures of all the angles of a triangle is 180°.

Therefore,
