Answer:

angles A and B = 65° angles C and D= 115

Step-by-step explanation:

angle A = angle B so

180-50=130

130/2=65

Complete the equation of the line whose slope is -2 and y intercept is (0,3)​
gavmur [86]

Answer:

y = -2x+3

Step-by-step explanation:

This is assuming you want the answer in slope-intercept (y = mx+b)

You need to know:

y = The line

m = The slope

b = The y-intercept

Step 1, replace the slope (m):

y = -2x+b

Step 2, replace the y-intercept (b):

y = -2x+3

Conclusion to 'complete the equation of the line whose slope is -2 and y intercept is (0,3)': y = -2x+3

Sin theata=3/5, then cos theata= ?
Elena-2011 [213]

\bf sin(\theta )=\cfrac{\stackrel{opposite}{3}}{\stackrel{hypotenuse}{5}}\impliedby \textit{let's find the \underline{adjacent side}}
\\\\\\
\textit{using the pythagorean theorem}
\\\\
c^2=a^2+b^2\implies \sqrt{c^2-b^2}=a
\qquad
\begin{cases}
c=hypotenuse\\
a=adjacent\\
b=opposite\\
\end{cases}
\\\\\\
\sqrt{5^2-3^2}=a\implies \pm\sqrt{25-9}=a\implies \pm 4=a
\\\\[-0.35em]
\rule{34em}{0.25pt}\\\\
~\hfill cos(\theta )=\cfrac{\stackrel{adjacent}{\pm 4}}{\stackrel{hypotenuse}{5}}~\hfill

Can someone please answer these 2 questions.
Volgvan

Answer:

The cross section of sphere is circle

Area of cross section = 25 in²

Step-by-step explanation:

From the figure we can see a cylinder with height 8 inches and volume 200 π in³.

<u>The cross section of the cylinder looks like a circle.</u>

<u>To find the area of cross section</u>

Volume of cylinder = Cross section area * Height

200 = cross section area * 8

cross section area = 200/8

 = 25 in²

Area of cross section = 25 in²
