An angle is denoted by the angle symbol ∠ and the three letters representing the name of the angle.
An angle is denoted by the angle symbol ∠ which is then being followed by three letters that will represent the points that form an angle.
Lets say for example, the expression ∠ABC will mean that “the angle is formed by the points A, B and C”
where the vertex of the angle is at the point B as it is in the middle.
Angles can also be of different types like:
An Acute Angle which means an angle is less than 90 degrees.
A Right Angle which means an angle which is exactly 90 degrees.
An Obtuse Angle which is an angle more than 90 degrees and less than 180 degrees.
A Straight Angle which is an angle that is exactly 180 degrees.
And a Reflex Angle which is an angle greater than 180 degrees and less than 360 degrees.
Therefore, an angle is denoted by the angle symbol ∠ and the three letters representing the name of the angle.

Answer:
<h2>
width = 3 feet</h2>
Step-by-step explanation:
Let h be the height of the door
and w be its width
The statement “The height of the door is I foot more than twice its width”
can be translated mathematically like this : h = 2w + 1
Let’s solve the equation for w:
h = 2w + 1
⇔ 2w = h - 1
![\Leftrightarrow w=\frac{h-1}{2}](https://tex.z-dn.net/?f=%5CLeftrightarrow%20w%3D%5Cfrac%7Bh-1%7D%7B2%7D)
now , if the door is 7 feet high then it’s width is equal to :
![\Rightarrow \frac{7-1}{2} =\frac{6}{2} =3 \ ft](https://tex.z-dn.net/?f=%5CRightarrow%20%5Cfrac%7B7-1%7D%7B2%7D%20%3D%5Cfrac%7B6%7D%7B2%7D%20%3D3%20%5C%20ft)
Answer:
it is possible to get something rational.
Step-by-step explanation:
This can't really be explained.
Answer:
Step-by-step explanation:
We know by the Triangle Angle-Sum Theorem that the angles of a triangle all add up to equal 180. So we find angle B:
180 - 82 - 55 = 43
So angle B = 43. Now we can use the Law of Sines to solve for side b:
![\frac{sin(55)}{8}=\frac{sin(43)}{b}](https://tex.z-dn.net/?f=%5Cfrac%7Bsin%2855%29%7D%7B8%7D%3D%5Cfrac%7Bsin%2843%29%7D%7Bb%7D)
Cross multiply to get
b sin(55) = 8 sin(43) and divide to solve for b:
so
b = 6.6605
The answer is 9 cm
Hope that helps! :)
