We know that lines e, and d are parallel. And they both cut through a straight line. Knowing that the bottom half are supplementary angles we know they will add up to 180 degrees. As you can see the congruent measurement on the left side of the equation is 154 degrees to find the measurement of angle
ANSWER: 26 degrees.

I hope this helps sorry for typos, this was on my phone and please thanks this reply and rate it if it did!

Add the following polynomial of x3+3xy-2×y2+y3,2×3-5x2y-3xy2-2y3

ANTONII [103]

The addition of the polynomial $x^{3}+3xy-2xy^{2} +y^{3}$ with $2x^{3}-5x^{2} y-3xy^{2}-2y^{3}$ is $3x^{3}+3xy-5x^{2} y-5xy^{2}-y^{3}$ .

What is a polynomial?

⇒ A polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables.

⇒ In the addition of polynomials, the like terms are added while in subtraction, the like terms are subtracted.

Calculation;

We have been given two polynomial which we have to add $x^{3}+3xy-2xy^{2} +y^{3}$ and $2x^{3}-5x^{2} y-3xy^{2}-2y^{3}$

The sign after addition or subtraction will always be of the variable having more value.

$(x^{3}+3xy-2xy^{2} +y^{3} )+(2x^{3}-5x^{2} y-3xy^{2}-2y^{3})$

On adding like terms with each other

⇒ $(x^{3} +2x^{3})+ 3xy-5x^{2} y-(2xy^{2}+3xy^{2})+(y^{3}-2x^{3})$

⇒ $3x^{3}+3xy-5x^{2} y-5xy^{2}-y^{3}$

Hence the addition of the polynomial $x^{3}+3xy-2xy^{2} +y^{3}$ and $2x^{3}-5x^{2} y-3xy^{2}-2y^{3}$ is $3x^{3}+3xy-5x^{2} y-5xy^{2}-y^{3}$ .
