Answer:x = 60

Step-by-step explanation:

The given triangle is an equilateral triangle. This is so because all the angles are equal. This also means that all the sides are equal.

The sum of the angles on a straight line is 180 degrees. Assuming each angle of the equilateral triangle is y degrees, it means that

y + 2x = 180

y = 180 - 2x

The sum of the angles in a triangle is 180 degrees. It means that

y + y + y = 3y = 180

This means that

3(180 - 2x) = 180

540 - 6x = 180

6x = 540 - 180 = 360

x = 360/60 = 60

Estimate the area

Savatey [412]

Answer:

Step-by-step explanation:

We are given that:

$f(x)\geq g(x)$

For all real numbers and they form a region R that is bounded from x = 1 to x = 7. A table of values is given.

We are directed to use a Right Riemann Sum to find the area between the curves of f and g.

Since f is greater than g for all values of x, to find the approximate area between f and g, we can first find the area of f and then subtract the area of g from f.

Using a Right Riemann Sum, the area of f is approximately:

(We multiply the width between each x-coordinate by the right endpoint)

$\displaystyle \int_1^7f(x)\, dx\approx3(5)+2(2)+1(8)=27$

And the area of g is approximately:

$\displaystyle \int_1^7g(x)\, dx\approx3(1)+2(0)+1(5)=8$

Therefore, the area between them will be:

$A=\displaystyle \int_1^7f(x)\, dx-\int_1^7 g(x)\, dx\approx 27-8=19$

Our answer is B.

26. Matthew factored a 5th-order polynomial. Four of the factors are: (x-2), (x+2i), (x-4), and (x+4) .

Keith_Richards [23]

Short Answer C
Remark
You may think there is no way to resolve this. Either of the first two look like they might work and you cannot be sure what you will get with the last two unless you know.

The answer is one of the last two. The equation cannot have just one or even a large number of complex numbers. When you are factoring a polynomial, the number of complex numbers must be even.

The complex root you have is x + 2i. Its partner is x - 2i
The complete equation would be
y = (x - 2i)(x + 2i) (x - 2)(x + 4)(x - 4)
I'll edit to add the graph.
