An isosceles triangle has an angle that measures 120°. Which other angles could be in that isosceles triangle? Choose all that apply.

a.40°

b.50°

c.70°

d.30°

C 30°

Step-by-step explanation:

All angles in a triangle add up to 180°

180 - 120 = 60

It's an isosceles triangle so, 2 sides are equal, 60° divided by 2 is 30°

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!
