Need help ASAP. i forgot all the steps after the Area is solved with 5. or if 25pi is the right answer.

maxonik [38]

Answer:

$42.5\:\mathrm{m^2}$

Step-by-step explanation:

The area of a sector with measure $\theta$ in degrees is given by $r^2\pi\cdot\frac{\theta}{360}$ , where $r$ is the radius of the sector.

What we're given:

$r$ of 5
$\theta$ of $195^{\circ}$

Solving, we get:

$A_{sector}=5^2\pi\cdot \frac{195}{360}=13.5416666667\pi=42.5424005174\approx \boxed{42.5\:\mathrm{m^2}}$

*Notes:

units should be in square meters (area)
the problem does not say whether to round or leave answers in term of pi, so you may need to adjust the answer depending on what your teacher specifically wants

X^2 - 25 = 25 solve for x

Nezavi [6.7K]

Answer:

$\tt x=\pm5\sqrt{2}$

Step-by-step explanation:

$\tt x^2 - 25 = 25$

$\tt x^2-25+25=25+25$ (Add 25 to both sides)

$\tt x^2=50$ ( Take square of both sides)

$\tt x=x=\sqrt{50},\:x=-\sqrt{50}$

$\tt x=\pm5\sqrt{2}$

What is the approximate angle of elevation when Brendon looks up at the tower?

Semmy [17]

Answer:

20 degrees

Step-by-step explanation:

I don't know why the 30 degrees was given at point A because you don't need that.

The equation is;

Sinx= Opposite/Hypotneuse

x = Sin inverse (50/146)

= 20.02

Rounded to 20 degrees
