23 is what percent of 184?

Brilliant_brown [7]

if we take 184 as the 100%, what is 23 off of it in percentage?

$\begin{array}{ccll} amount&\%\\ \cline{1-2} 184 & 100\\ 23& x \end{array} \implies \cfrac{184}{23}=\cfrac{100}{x} \\\\\\ 8=\cfrac{100}{x}\implies 8x=100\implies x=\cfrac{100}{8}\implies x=\cfrac{25}{2}\implies x=12.5$

If tanx-cotx=5 then what is the value of tan²x+cot²x

Roman55 [17]

Answer:

Step-by-step explanation:

note that tanx cotx = tanx × $\frac{1}{tanx}$ = 1

Given

tanx - cotx = 5 ( square both sides )

(tanx - cotx)² = 5² = 25 ← expand left side using FOIL

tan²x - 2tanxcotx + cot²x = 25

tan²x - 2 + cot²x = 25 ( add 2 to both sides )

tan²x + cot²x = 27
