Answer:
Linear Pair:
∠ 1 and ∠ 2
Vertical Angles:
∠ 1 and ∠ 3
Supplementary Angles:
∠ 7 and ∠ 6
Step-by-step explanation:
Linear Pair:
A linear pair of angles is formed when two lines intersect.
Two angles are said to be linear if they are adjacent angles formed by two intersecting lines.
The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.
Example
∠ 1 and ∠ 2 ∠ 8 and ∠ 5 ,etc
Vertical Angles:
The angles opposite each other when two lines cross.
They are always equal.
Example
∠ 1 and ∠ 3 ∠ 8 and ∠ 6 ,etc
Supplementary Angles:
Two Angles are Supplementary when they add up to 180 degrees.
Examples two angles (140° and 40°)
All Linear pair are Supplementary angles
Example
∠ 7 and ∠ 6 ∠ 8 and ∠ 5 ,etc
Answer:
srry think its to late
Step-by-step explanation:
Do this and then simplify the result
m=18 when r = 2.
Step-by-step explanation:
Given,
m∝![\frac{1}{r}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Br%7D)
So,
m = k×
,--------eq 1, here k is the constant.
To find the value of m when r = 2
At first we need to find the value of k
Solution
Now,
Putting the values of m=9 and r = 4 in eq 1 we get,
9 = ![\frac{k}{4}](https://tex.z-dn.net/?f=%5Cfrac%7Bk%7D%7B4%7D)
or, k = 36
So, eq 1 can be written as m= ![\frac{36}{r}](https://tex.z-dn.net/?f=%5Cfrac%7B36%7D%7Br%7D)
Now, we put r =2
m = ![\frac{36}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B36%7D%7B2%7D)
or, m= 18
Hence,
m=18 when r = 2.
