Answer:
I think is 54
Step-by-step explanation:
18times 3 =54
Answer: 
Step-by-step explanation:
Given the equation
you need to solve for the variable "b".
You need to apply Distributive property on both sides of the equation:

Now you need to add 21 to both sides of the equation:

Subtract
from both sides:

And finally, you can divide both sides of the equation by 18:

Answer:
Acute
Step-by-step explanation:
Answer:
If P = (x,y) then formulas for each trigonometric functions are:
sin x = y/r
cos x = x/r
tan x = y/x
cot x = x/y
sec x = r/x
cosec x = r/y
where r = √(x²+y²).
First find r:
r = √(13²+84²)=√(169+7056)=√7225=85.
Then just substitute:
sin x = 84/85
cos x = 13/85
tan x = 84/13
cot x = 13/84
sec x = 85/13
cosec x = 85/84
