Answer: 
<u>Step-by-step explanation:</u>
Note the following identities: tan² x = sec²x - 1

tan² x + sec x = 1
(sec² x -1) + sec x = 1
sec² x + sec x - 2 = 0
(sec x + 2)(sec x - 1) = 0
sec x + 2 = 0 sec x - 1 = 0
sec x = -2 sec x = 1

To find the sum of the interior angles of a nonagon, divide it up into triangles... There are seven triangles... Because the sum of the angles of each triangle is 180 degrees... We get
7 * 180 = 1260°
So, the sum of the interior angles of a nonagon is 1260 degrees.

= 21
First, simplify

to

/ Your problem should look like:

= 21
Second, multiply both sides by 8. / Your problem should look like: -7k = 167
Third, divide both sides by -7. / Your problem should look like: k =
Fourth, simplify

to

/ Your problem should look like: k =
Fifth, simplify

to 24. / Your problem should look like: k = -24
Answer:
k = -24
Answer:
3 are mushed
Step-by-step explanation:
You have 12 tomatoes
All but 9 get mushed
Total tomatoes = mushed + non mushed
12 = mushed +9
Subtract 9 from each side
12-9 = mushed+9-9
12-9 = mushed
3 = mushed
