If two parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent.

Value of X is  9 and  Angle 6 is  79°

If two parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent.

If two parallel lines are cut by a transversal, then the pairs of alternate interior angles are congruent.

If two parallel lines are cut by a transversal, then the pairs of alternate exterior angles are congruent.

Since, angle 1 and angle 4 are vertically opposite angles . Hence, these are equal.

∠1 = ∠4 = 11x + 2

Similarly, ∠6 and ∠7 are vertically opposite angles.

Thus,  ∠6 = ∠7 = 8x + 7

If two parallel lines are cut by a transversal, then the sum of interior angles on one side is equal to 180 degree.

Therefore,   ∠4 + ∠6 = 180

                 11x + 2 + 8x + 7 = 180

                  19x + 9 = 180

                  19x = 171

                   x = 9

Value of angle 6 = value of angle 7

                           = 8x + 7

                        = 8 (9) + 7

                        = 79 Degree

xxMikexx [17]

Answer and Step-by-step explanation:

The answer is 2 (which is equal to x).

If you were to plug 2 in to the function, the result if 30.

x^{3}+ 6x^{2} -x\\\\\\\\(2)^3+6(2)^2 - 2 = 30 = f(2)
