Given the point (3, 4), which of the following shows that sinxcscx = 1?
yawa3891 [41]
\bf sin(\theta)=\cfrac{opposite}{hypotenuse}\qquad csc(\theta)=\cfrac{hypotenuse}{opposite}\\\\
-------------------------------\\\\
\begin{array}{clclll}
3&,&4\\
\uparrow &&\uparrow \\
x&&y\\
a&&b\\
adjacent&&opposite\\
side&&side
\end{array}\qquad 
\begin{array}{llll}
\textit{using the pythagorean theorem}
\\\\\\
c^2=a^2+b^2\implies c=\sqrt{a^2+b^2}
\end{array}
\\\\\\
hypotenuse\implies  c=\sqrt{3^2+4^2}\implies c=\sqrt{25}\implies \boxed{c=5}\\\\
-------------------------------\\\\

\bf sin(x)=\cfrac{4}{5}\qquad csc(x)=\cfrac{5}{4}\implies sin(x)csc(x)\implies \cfrac{4}{5}\cdot \cfrac{5}{4}\implies 1

SCORPION-xisa [38]

Answer:

100 units^2

Step-by-step explanation:

a^2+b^2=c^2

8^2+6^2=c^2

64+36=c^2

100=c^2 (area of square)

10=c (length of hypotenuse)

Therefore, the area of the square is 100 units^2

What is 87 less than the quotient of an unknown number and 43 is -75.
frosja888 [35]
We set up an equation: ?/43 -87= -75
⇒ ?/43= -75+ 87
⇒ ?/43= 12
⇒ ?= 12*43
⇒ ?= 516

The unknown number is 516~
