Answer:
Step-by-step explanation:
From the previous answers you know the angles and side lengths of the triangle:
α = 60°
Ф = 30°
and the side lengths:
1,2 and √3.
Remember:
sin = opposite / hypotenuse
cos = adjacent / hypotenuse
tan = opposite / adjacent
Now you can read off from the triangle:
sin 30° = 1/2
cos 60° = 1/2
sin 60° = √3/2
cos 30° = √3/2
tan 30° = 1/√3
tan 60° = √3
Answer:
and 
.
Step-by-step explanation:
To this relation be a function, the horizontal coordinates can't be equal. So, let's find the value of 
that makes those coordinates equal.
Using the null factor property, we have
Therefore, the given relation is not a function when and .
The answer should be n= 1500
Answer: 600
Step-by-step explanation: 6!x5!= 86400| 4!x3!= 144| 86400/144= 600
Hope it’s right!
