Anormal line is a line that is perpendicular to another line, curve or surface. give an everyday example of a normal line to each of the following: another line, a circle, a plane.

Here are the examples for

1. a normal line to a line

2. A normal line to a circle

A circular plate balanced on a scale

3. A normal line to a plane

∞ this is your sign

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
