Answer:16 and 18
Step-by-step explanation:
16x16=256
18x18=324

Answer:
x = 15
Step-by-step explanation:
Hope this helps! :D
(x+16)²+(y−13)²=36
The given equation is of a circle.
comparing it with general equation, radius r =6
so the lam post can detect upto 6 feet .
The smallest will be 90 degree
Answer:
-cot(x)
Step-by-step explanation:
tanx-(sec^2x / tanx)
Lets get a common denominator of tan
tan x * tan x/ tan -sec ^2 x/ tan x
tan ^2 x - sec ^2 x
---------------------------
tan x
We know than sec^2 - tan^2 =1 (trig identity) so factor out -1
-1(-tan ^2 x + sec ^2 x)
---------------------------
tan x
-1(1)
---------------------------
tan x
-1
----------
tan (x)
We know 1/ tan x = cot (x)
- cot(x)
