Step-by-step explanation:

BAC=20°

BCA=90°

BC=3(P)

AB=?(H)

NOW,

SinΘ=P

Sin 20°=3

0.342=3

AB=3

0.342

AB=8.77

F the value of x decreases by 6, how does the value of m(x + 9) change?

Yuki888 [10]

start with y= m(x+9)

Use the distributive property:

y= mx+9m

Now you want x to decrease by 6:

so y ' = m(x-6) + 9m

Use distributive property again:

y'= mx - 6m + 9m

y' = (mx+9m) - 6m

y' = y - 6m

So the value of y decreases by 6m.

Use the squared identities to simplify 2sin^2xcos^2x

Rainbow [258]

$\bf sin^2({{ \theta}})=\cfrac{1-cos(2{{ \theta}})}{2}\qquad \qquad 

cos^2({{ \theta}})=\cfrac{1+cos(2{{ \theta}})}{2}\\
-----------------------------\\
thus
\\\\
2sin^2(x)cos^2(x)\implies \boxed{2}\cdot \cfrac{1-cos(2{{ x}})}{\boxed{2}}\cdot \cfrac{1+cos(2{{ x}})}{2}
\\\\
\cfrac{1-cos(2{{ x}})}{1}\cdot \cfrac{1+cos(2{{ x}})}{2}\implies 
\cfrac{[1-cos(2x)][1+cos(2x)]}{2}\\
-----------------------------\\
\textit{now recall}\implies \textit{difference of squares}
\\ \quad \\
$

$\bf (a-b)(a+b) = a^2-b^2\qquad \qquad 
a^2-b^2 = (a-b)(a+b)\\
-----------------------------\\
thus
\\\\
\cfrac{[1-cos(2x)][1+cos(2x)]}{2}\implies \cfrac{1^2-cos^2(x)}{2}
\\\\
 \cfrac{1-cos^2(x)}{2}\impliedby 
\begin{array}{llll}
\textit{pretty sure you know what that numerator is}\\
\textit{check your pythagorean identities}
\end{array}$
