HELP DUE IN 5 MINS!

Solve for x in the polygon below.

x=?? degrees

135

Step-by-step explanation:

540-75-120-120-90=135

x = 135

Step-by-step explanation:

Total sum of interior angles of a pentagon = 540

75 + 120 + 120 + 90 + x = 540

405 + x = 540

=> Subtract 405 on both sides of "="

x = 135

Hope this helps!

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!
