The value of QR is 11
<h3>How to determine the length of QR?</h3>
The given parameters are:
RS = 5
QS = 16
Because R is on QS, then we have:
QS = QR + RS
This gives
16 = 5 + QR
Evaluate
QR = 11
Hence, the value of QR is 11

Answer:B. 1
Step-by-step explanation:
If it has more than 1 it won’t be a triangle anymore.
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)
We need to find the percentage of the extra feet that she measured, so first we have to find out how much that is. We can do this by simply subtracting:
4.27 - 4 = 0.27
Now we can set up a proportion to find the percentage.

Solve for x
0.27 x 100 = 27
27/4 = 6.75
The answer is
6.75% :)
