Answer:

Angle E is the included angle between the sides FE and DE

The included angle between sides FE and DF is the angle F

Step-by-step explanation:

we know that

An<u> included angle</u> is the angle between two sides of a triangle

In the triangle DEF

we have

The included angle F is the angle between the sides FE and FD

The included angle E is the angle between the sides FE and DE

The included angle D is the angle between the sides DF and DE

therefore

In this problem

Angle E is the included angle between the sides FE and DE

The included angle between sides FE and DF is the angle F

What is the measure of angle x?
Kitty [74]

The two horizontal lines are parallel.

This makes the 80 degree angle and the angle ox x and 20 degrees are alternate interior angles and are the same.

This means x + 20 needs to equal 80.

X = 80-20 = 60 degrees.

Vesna [10]
The answer is X = 11 - 3. This is because to calculate the original value of how many books Isabella had, you have to take away the amount purchased from the overall total amount. Therefore, the equation is x = 11-3

Given the polynomial 2x3 + 18x2 − 18x − 162, what is the value of the coefficient 'k' in the factored form?2x3 + 18x2 − 18x − 16
s344n2d4d5 [400]

Answer:

k=3

Step-by-step explanation:

Let

f(x)=2x^3+18x^2-18x-162

We factor 2 to obtain;

f(x)=2(x^3+9x^2-9x-81)

We factor the polynomial within the parenthesis by grouping.

f(x)=2(x^2(x+9)-9(x+9)

f(x)=2(x^2-9)(x+9)

f(x)=2(x^2-3^2)(x+9)

We apply difference of two squares on the second factor: x^2-3^2=(x-3)(x+3)

f(x)=2(x+3)(x-3)(x+9)

We now compare to;

f(x)=2(x+k)(x-k)(x+9)

It is now obvious that k=3
