Angle three would also be thirty, and the other two angles (2+4) would be 180 (the degrees in a straight line ALWAYS) minus 30, which would be 150. The answer your looking for would be 30 though.

The perimeter of a quarter circle is 7.14 feet. What is the quarter circles radius

egoroff_w [7]

if the perimeter of 1/4 of the circle is 7.14, then the full circle is 4(7.14) = 28.56.

$\bf \textit{circumference of a circle}\\\\ C=2\pi r~~ \begin{cases} r=radius\\ \cline{1-1} C=28.56 \end{cases}\implies 28.56=2\pi r \\\\\\ \cfrac{28.56}{2\pi }=r\implies 4.55\approx r$

and the radius is the same on any location of the circle.

(-20,-4), (-12, -10)<br> find the slope

love history [14]

Answer:

-6/8

Step-by-step explanation:

The slope formula is y2-y1

____

x2-x1

In the ordered pair (-20,4)

-20 is x1 the first x and 4 is x1

-12 is the x2 i.e. 2nd point and -10 is y2 i.e. 2nd point on y axis

so we plug in the value to the formula -10-(-4) two negatives become +

_____

-12-(-20)

so -10+4 -6 6

____ = ___ = - _

-12+20 8 8

(remember you subtract and the signs are different you subtract and use the sign of larger number)
