In this PARALLELOGRAM, what is the measure of Angle D?

enot [183]

Answer:

Step-by-step explanation:

The parallelogram is divided into two triangles. Remember, angles in a triangle add up to 180 degrees. That being said, take the sum of the numbers given in triangle ABC and subtract it from 180.

60 + 28 = 88

180 - 88 = 92 (this is the measure of angle B)

Angles D and B are congruent, which means they are the same.

Since Angle B is 92 degrees, then D is 92 degrees also.

N=4; 2i and 3i are zeros <br> f(-1)=50

Nonamiya [84]

Solution:- $\text{Let f(x) be any nth degree polynomial with n=4}\\$

$\text{Given that 2i and 3i are the zeroes of f(x)}$

$\text{so (x-2i) and (x-3i) are factors of f(x)}$

$\text{Since 2i is a zero of f(x) then its conjugate -2i is also a zero of f(x)}$

$\Rightarrow(x+2i) \text{is a factor}\\\text{Similarly, conjugate of 3i is -3i is also a zero of f(x) }\\\Rightarrow(x+3i)\text{is a factor}\\\text{So , }\\f(x)=k(x-2i)(x+2i)(x-3i)(x+3i)\\=k(x^2-(2i)^2)(x^2-(3i)^2)\\=k(x^2-4i^2)(x^2-9i^2)\\=k(x^2+4)(x^2+9)\\=k(x^4+13x^2+36)\\\text{As given}\\f(-1)=50\\\Rightarrow k((-1)^4+13(-1)^2+36)=50\\\Rightarrow k(1+13+36)=50\\\Rightarrow k(50)=50\\\Rightarrow k=1\\\text{So by substituting k=1 in f(x) we get ,}\\f(x)=(x^4+13x^2+36)$

The price of a notebook is 20% less than the price of a book. By what percent is the price of the book higher than the price of

TiliK225 [7]

The price of the book is 125% higher than the price of the notebook if the price of a notebook is 20% less than the price of a book.

<h3>What is the percentage?</h3>

It is defined as the ratio of two numbers expressed in the fraction of 100 parts. It is the measure to compare two data, the % sign is used to express the percentage.

Let x is the price of the book

And y is the price of the notebook,

Then,

y = x- 0.20x = 0.80x

x = (1/0.80)y

x = 1.25y

So x is 1.25 or 125% higher than the, y

Thus, the price of the book is 125% higher than the price of the notebook if the price of a notebook is 20% less than the price of a book.
