Answer:

26 cm

Step-by-step explanation:

The sides of the quadrilateral are tangents to the circle.

Tangents drawn from an external point to the circle are congruent, hence

Beginning from the left side of the quadrilateral and counting anti- clockwise

3 + 4 + 4 + 4 + 4 + 2 + 2 + 3 = 26 cm

Answer:

The perimeter of the red polygon is 26 cm.

Step-by-step explanation:

We are given a figure. From the figure, the sides of the quadrilateral are tangents to the circle. So, tangents to the circle from a same point measures the equal length.

I have attached the figure with the measures.

Now let's find perimeter of the red polygon. The red polygon is nothing but a quadrilateral.

To find the perimeter, we need to add all the sides of the polygon.

Perimeter =

4 + 4 + 4+ 2 + 2+ 3+ 3+ 4 = 26 cm.

So the perimeter of the red polygon is 26 cm.

6x2 + 5x + 1 how do I factor this out?

Oduvanchick [21]

Answer:

(3x + 1) (2x + 1)

Step-by-step explanation:

ax² + bx + c can be factored using the AC method:

1. Multiply a and c.

2. Find factors of ac that add up to b.

3. Divide each factor by a; reduce the fractions.

4. The denominator is the coefficient, the numerator is the constant.

6x² + 5x + 1

1. ac = 6 × 1 = 6

2. Factors of 6 that add up to 5: 2 and 3.

3. 2/6 = 1/3, and 3/6 = 1/2

4. The factors are 3x+1 and 2x+1.

6x² + 5x + 1 = (3x + 1) (2x + 1)

The measure of an exterior angle of a regular polygon is 2x, and the measure of an interior angle is 4x. Using the relationship

torisob [31]

The value of x is 30

Solution:

Given that measure of exterior angle of regular polygon is 2x

The measure of interior angle is 4x

To find: value of x

The sum of an interior angle plus an exterior angle must be equal to 180 degrees (supplementary angles)

measure of exterior angle + measure of interior angle = 180

2x + 4x = 180

6x = 180

x = 30

Finding the measure of an exterior angle

measure of exterior angle = 2x = 2(30) = 60 degrees

Finding the measure of interior angle

measure of interior angle = 4x = 4(30) = 120 degrees

What is the area of major sector DFE?

melomori [17]

Answer:

B. 171.74 cm²

Step-by-step explanation:

Area of a sector = $\frac{\theta}{360} \times \pi r^2$ .

Where,

$\theta = 260$

radius (r) = 8.7 cm

Plug in the values into the formula

Area of sector = $\frac{260}{360} \times \pi 8.7^2$

Area of sector = $\frac{260 \times \pi 75.69}{360}$

Area of sector = 171.74 cm² (approximated)
