What is the measure of 1?

90°
80°
85°
95°

C. 85

Step-by-step explanation;

You know that that sum of the angle measures in a quadrilateral is 360°, so you can solve for the missing angle measure.

So, you can see the bottom left corner equals 90 degrees because of the right angle. The other degrees plus 90 equals 275. So we would subtract 275 from 360 and get 85.

This means that "1" equals 85 degrees.

I hope this helps!

step-by-step explanation:

idk the answer i want to say 10 but then it would be equal so try 9 but then yeah so yeah we love edgen

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!
