(P+T)-7 = 6. 7 less than, meaning taking away 7 from the sum of (P + T) is as much as / equal to 6
Answer:

Step-by-step explanation:
The equation of the circle with center A=(a,b) and radius = r are:

When A=(3,-2) and radius=r=-5

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
Answer:

Step-by-step explanation:

<u>211 - 87.40</u> equals 123.60.
To see if your answer is correct just <u>add 123.60 and 87.40 together</u>.
