The two angle measures are equal (which is the point of an angle bisector), so you have
  y + 30 = 3y - 50
  30 = 2y - 50 . . . . . . . . subtract y
  80 = 2y . . . . . . . . . . . . add 50
  40 = y . . . . . . . . . . . . . .divide by the coefficient of y

The value of y is 40.

Which expressions are polynomials??
GrogVix [38]

Answer:

Options (1) and (2)

Step-by-step explanation:

Properties of a polynomial,

1). A polynomial having division by a variable can't be defined as a polynomial.

  Example:

   (y² + \frac{x}{1+x})

2). A polynomial can't have a negative exponent.

  Example : (x^{-2}+y-6)

3). Polynomials don't have the radicals.

  Example : y² + x√3

4). A polynomial can't have a fraction exponent.

   Example : x^2+x^{\frac{1}{2}}-1

By these properties, Options (3) and (4) are not the polynomials.

Options (1) and (2) are the correct options.
