Angles 1 and 8 are created by line t intersecting with line m.


Line t is called a transversal line, because it intersects 2 parallel lines.

t divides the straight angle formed by m alone, forming the linear pair of angles (1) and (8), whose sum is 180 °, that is they are supplementary.


Answer: (1) and (8) are linear pairs

Because 1 and 8 are on a line and are a linear pair, that makes them supplementary. Linear pair definition is the reason.

Hope this helps!!

A circular garden has a diameter of 6 feet. Which of the following is closest to the area of the garden?
oksian1 [2.3K]
The answer to this problem is 'B'.

This is because to find the area of a circle your formula is
A = 3.14•r²
So your first step is

1. Find the radius by dividing the diameter (6) by 2
6/2 = 3 Radius= 3

Now that you have found the radius (3) plug the number in the formula
2. A = 3.14•3²
OR
A = 3.14•3•3

Finally, solve the last step - Find the area
3.14 • 3 • 3 = 28.26
A = 28.26
