quadrilateral abcd is inscribed in this circle.

what is the measure of angle c?

enter your answer in the box.

°

<C = 107°

Step-by-step explanation:

2x - 4 + 3x + 9 = 180

5x + 5 = 180

5x = 175

x = 35

<A = 2(35) + 3 = 73

<B = 2(35) - 4 = 66

<D = 3(35) + 9 = 114

<C = 360 - (73 + 66 + 114)

<C =360 - 253

<C = 107

step-by-step explanation:

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
