Rotating 180° would be changing (x to -x and y to -y) therefore, X’ (-3, -4)
Answer:
The value of a is 7.4833. The value of
and
.
Step-by-step explanation:
Consider the provided information.
The required figure is shown below:
We need to find the value of a.
Calculate the value of a by using Pythagorean theorem.





Hence, the value of a is 7.4833.
Now find the value of angle A as shown:




Find the value of angle B as shown:




Hence, the value of
and
.

<h3>3D shapes</h3>
- Cube Cuboid
- Sphere Square-based pyramid
- Cylinder Triangular prism
- Pentagonal pyramid Hexagonal prism

<em><u>A solid of revolution is a three-dimensional figure obtained by rotating a two-dimensional figure (or curve) around a straight line (called the axis) that lies in the same plane. ... Since the triangle's interior is shaded, it creates the interior of the cone, creating a solid figure.</u></em>
<em><u>Three dimensional shapes are obtained by rotating the two dimensional shapes. When a circle is rotated we get sphere; when a triangle is rotated we get cone; when rectangle or square is rotated we get cylinder</u></em>

If one-sixth of a certain number is four more than one-twelfth the number, the required number will be 48.
Let the unknown number be 'a'
One-sixth of the number is expressed as 1/6 a ..... 1
One-twelfth the number is also expressed as 1/12 a
Four more than one-twelfth the number will be written as:
1/12 a + 4 .... 2
Equating 1 and 2 will give:
1/6 a = 1/12 a + 4
a/6 = a/12 + 4
Collect the like terms

Find the LCM

Cross multiply
a = 12×4
a = 48
This shows that the required number is 48
