The Answer: x = -2/7

yulyashka [42]3 years ago
7 0

Answer: x = 2/7 or 0.29

Step-by-step explanation:

- 2x - 12 = 5x - 10

- 2x - 5x = 12 - 10

- 7x = 2

x = 2/7 or x = 0.29

The decimal place is rounded up.

What are the lateral area and the surface of the cone shown below?
Ierofanga [76]
\bf \textit{lateral surface area of a cone}\\\\
LA=\pi r\stackrel{slant~height}{\sqrt{r^2+h^2}}~~
\begin{cases}
r=radius\\
h=height\\
-------\\
r=11\\
\stackrel{slant~height}{\sqrt{r^2+h^2}}=24
\end{cases}\implies LA=\pi (11)(24)
\\\\\\
\boxed{LA=264\pi }\\\\
-------------------------------

\bf \textit{total surface area of a cone}\\\\
SA=\pi r\stackrel{slant~height}{\sqrt{r^2+h^2}}+\pi r^2~~
\begin{cases}
r=radius\\
h=height\\
-------\\
r=11\\
\stackrel{slant~height}{\sqrt{r^2+h^2}}=24
\end{cases}
\\\\\\
SA=\pi (11)(24)+\pi (11)^2\implies SA=264\pi +121\pi 
\\\\\\
\boxed{SA=385\pi }

Can someone help me with this please
jenyasd209 [6]

To solve the first question, the angles J and K are perpendicular to each other, that means also that the angles are 90 degrees.

Apart from each other.

This is the total angle measure, that means the sum of the smaller angles must equal 90 degrees.

So the expression would be

2x - 9 + 27 = 90

2x + 18 = 90

2x = 90 - 18

2x = 72

X = 72/2 = 36 degrees.

For the second question since w and v are parallel that means the angles are equal to each other


Thus make the expressions and value equal to each other and solve for x

3x + 60 = 120

3x = 60

X = 20 degrees.
