Answer:

The answer is 122 degrees

Step-by-step explanation:

corresponding angles have together 180 degrees so the answer would be 180 - 58 =122 degrees

The complete question in the attached figure

we have that
m∠1=58°
m∠7=?
we know that
m∠1+m∠3=180°------------> supplementary angles
and
m∠3=m∠7--------------------> corresponding angles
then
m∠3=180°-m∠1-----------> m∠3=180°-58°=122°

m∠7=m∠3=122°

the answer is m∠7=122°

Korvikt [17]

Answer:

The volume is 997.62 cubic units..

Step-by-step explanation:

We are given the following details:

The pyramid has a regular hexagonal base i.e. each side of hexagon is equal.

Side of hexagonal base, a = 8 units

Altitude of pyramid, h = 18 units

We have to find the volume of pyramid.

Formula:

$V = \dfrac{1}{3} \times B \times h$

Where, B is the area of base of pyramid.

h is the height/altitude of pyramid

To calculate B:

Here, base is a hexagon with side 8 units.

$\text{Area of hexagon, B }= 6 \times \dfrac{\sqrt{3}}{4}a^{2}$

Here, a = 8 units

$\Rightarrow B = 6 \times \dfrac{\sqrt{3}}{4}\times 8^{2}\\\Rightarrow B = 166.27\text{ square units}$

Putting values of B and h in Formula of volume:

$\Rightarrow V = \dfrac{1}{3} \times 166.27 \times 18\\\Rightarrow V = \dfrac{2992.89}{3} = 997.62\text{ cubic units}$

Hence, the volume is 997.62 cubic units.

Answer:

-2

Step-by-step explanation:

The solution to the system is where the lines cross. The x-coordinate of that point is its horizontal distance from the y-axis.

The solution is (x, y) = (-2, 2). The x-coordinate is -2.

The expression for volume is l•w•h (length times width times height). For example, you could say:
Amber is filling a cube with sand. She wants to find out the volume of the box to find out how much sand she needs. She knows that the length is 7 inches, the width is 3 inches, and the height is 4 inches. What is the volume of the cube?
