Radii and chord form an equilateral triangle. The angle of the larger segment is $360^o-60^o=300^o$ .

The length of the larger segment is

$l= \frac{2r\pi\alpha}{360^o}= \frac{2\times 8\pi300^o}{360^o}= \frac{ 16\pi5}{6}= \frac{ 8\pi5}{3}=\frac{ 40\pi}{3}$

Solve the inequality

Kryger [21]

2(4 + 2x) ≥ 5x + 5

Simplify.

8 + 4x ≥ 5x + 5

Subtract 8 from both sides, as well as subtracting 5 from both sides.

4x - 5x ≥ 5 - 8

Simplify.

-x ≥ -3

Divide both sides by -1.

x ≤ 3

From a point 80 feet in front of a library, the angles of elevation to the base of a flagpole, and to the top of the flag are 22

ddd [48]

check the picture below.

$\bf tan(22^o)=\cfrac{x}{80}\implies \boxed{80tan(22^o)=x}
\\\\[-0.35em]
~\dotfill\\\\
tan(43.5^o)=\cfrac{y+x}{80}\implies 80tan(43.5^o)=y+x\implies 80tan(43.5^o)-x=y
\\\\\\
80tan(43.5^o)-80tan(22^o)=y\implies 43.59506727037783689501 \approx y

Answer:

See Below.

Step-by-step explanation:

We want to verify:

$\cos(x-y)-\cos(x+y)=2\sin(x)\sin(y)$

We will utilize the following identities:

$\cos(x-y)=\cos(x)\cos(y)+\sin(x)\sin(y)$

And:

$\cos(x+y)=\cos(x)\cos(y)-\sin(x)\sin(y)$

So, by substitution, we acquire:

$(\cos(x)\cos(y)+\sin(x)\sin(y))-(\cos(x)\cos(y)-\sin(x)\sin(y))=2\sin(x)\sin(y)$

Distribute:

$\cos(x)\cos(y)+\sin(x)\sin(y)-\cos(x)\cos(y)+\sin(x)\sin(y)=2\sin(x)\sin(y)$

The first and third term will cancel:

$\sin(x)\sin(y)+\sin(x)\sin(y)=2\sin(x)\sin(y)$

Combine like terms:

$2\sin(x)\sin(y)\stackrel{\checkmark}{=}2\sin(x)\sin(y)$
