Tan x = sin x / cos x
cot x = cos x/ sin x
We can see that tan and cot are reciprocal.
So, if tan(O) = -(3)/(8), then cot(O) = - (8)/3.
Answer:

Step-by-step explanation:
Given:

The best way to write a polynomial with three terms as a product of binomials is to FACTOR!
The middle number is 3 and the last number is -4.
Factoring means we want something like

We need two numbers that...
ADD together to get 3 and
MULTIPLY together to get -4
Test the numbers -1 and 4:

These are the right numbers! Now, I can write them as factored binomials!

Answer:
Ok look times 18 and 10 then what ever you get with that times it with 12
Step-by-step explanation:
She can use 68 + 20 = 88 to help by noticing that the 20 is ahead of 19 by 1. She can easily mentally turn the 20 into a 19 and realized that the 88 would become 87.
