Answer:

x = 90

Step-by-step explanation:

<u><em>Here 60 is angle B, 30 is Angle a, B is The third angle of the triangle, and x is the exterior angle measurement! </em></u>

<u><em /></u>

60 + 30 + b= 180

a + x = 180

60 + 30 + b= 180

90 + b = 180

b = 90

90 + x = 180

x = 90

<h2>Note: </h2>

exterior angle  equal to the sum of its<em> two opposite non-adjacent interior angles.</em>

Make a conjecture: How many solutions does a quartic equation x 4 + ax 3 + bx 2 + cx + d = 0 have? Explain.
Ratling [72]

Answer:

Four

Step-by-step explanation:

The degree of a polynomial is the highest of the degree of the monomials with non-zero co-efficient. In this problem we are given the polynomial:

                 $ x^4 + ax^3 + bx^2 + cx + d = 0 $

The degree of the polynomial is 4.

For a polynomial of <em>n- degree </em>we have <em>n solutions counting multiplicity</em>.

So for this four degree polynomial we would have 4 solutions. Could be real or complex depending on the equation.
