Answer:

Hexagonal Prism

Answer:

x = 8 , ∠ B = 70°

Step-by-step explanation:

∠ A and ∠ B are alternate exterior angles and are congruent, that s

8x + 6 = 4x + 38 ( subtract 4x from both sides )

4x + 6 = 38 ( subtract 6 from both sides )

4x = 32 ( divide both sides by 4 )

x = 8

Then

∠ B = 4x + 38 = 4(8) + 38 = 32 + 38 = 70°

Step-by-step explanation:

12x1/2=24

24/6=4

h=4

Height of trapezoid is,

⇒ h = 4 km

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

The area of the trapezoid is 24 Square km.

We know that;

Area of Trapezoid = (a + b) h / 2

Here, A = 24 km² , a = 3 km , b = 9 km

Hence, We get;

24 = (3 + 9) h / 2

48 = 12h

h = 48 / 12

h = 4 km

Thus, Height of trapezoid is,

⇒ h = 4 km

Answer:

12

Step-by-step explanation:

One property of a parallelogram is that diagonals bisect each other. This means that it "divides" each other in to two equal parts.

Since FK is 6, that means that KH is also 6.

Then you have to add both of those because FK and KH both make up the diagonal FH, FH is 12.

Answer:

the surface area of the square pyramid is 576.66 cm^2

Step-by-step explanation:

The computation of the surface area of square pyramid is given below:

A = a^2  + 2a × √a^2 ÷ √4 + √h^2

where

a = 12 cm

h = 17 cm

Now put the value of a and h in the above formula

= 12^2 + 2(12) × √12^2 ÷ √4 + √17^2

= 576.66 cm^2

hence, the surface area of the square pyramid is 576.66 cm^2

Step-by-step explanation:

The equation for triangle 2 will be: a² + b² = n².

What is Pythagorean theorem?

Pythagorean theorem states that for a right-angle triangle, the sum of the squares of the base and the height is equal to the square of the hypotenuse of that triangle.

Here, the angle between side: a and side: b is a right-angle.

Therefore, we can consider side: a as the height and side: b as the base of the triangle.

Therefore we can write as per the Pythagorean theorem:

(Base)² + (Height)² = (Hypotenuse)²

Hence, a² + b² = n²

Shaded region is the difference of the areas of the parallelogram and the square:

Answer:

area of shaded region=1125m²

Solution given:

base of parallelogram [b]=45m

height of parallelogram [h]=30m

length of square [l]=15m

we have

Area of shaded region =Area of {parallelogram -square]

=b×h-l²=45×30-15²=1125m²

Answer:

∠JKP = 35°

Step-by-step explanation:

since P is the incenter, then lines to incenter bisect the corner angles:

7x - 6 = 5x + 4

subtract 5 x from both sides of the equation:

2x - 6 = 4

add 6 to each side:

2x = 10

divide both sides by 2:

x = 5

∠KJP = 7(5) - 6 = 29°

∠LJP = 5(5) + 4 = 29°

then ∠KJL = 29° + 29° = 58°

∠KLJ = 26° + 26° = 52°

∠JKL = 180° - 58° - 52° = 70°

∠JKP = 1/2 ∠JKL = 1/2(70°) = 35°

there might be a more direct way about it but this was the least confusing way I know to explain it.

Answer:

1. (x - 7)(x + 3)

Step-by-step explanation:

x^2 - 4x – 21

We need two numbers that have a product of -21 and a sum of -4.

The numbers are -7 and 3 since -7 * 3 = -21, and -7 + 3 = -4

x^2 - 4x – 21 = (x - 7)(x + 3)

Answer: (x - 7)(x + 3)

Answer:

1

Step-by-step explanation:

X²-4x-21

-21×x²=-21x²

the factors of -4x and -21x² are -7x and 3x

x²-7x+3x-21

(x²-7x)+(3x-21)

X(x-7)+3(x-7)

3b + 8 - 8 ≥ 14 -8

3b ≥ 6

Dividing both sides by 3

b ≥ 2

The value of b is greater than and equal to 2.
