Answer:

x = 6.5

Step-by-step explanation:

In a triangle, the sum of the measures of the angles equals 180 deg.

8x + 10x - 10 + 10x + 8 = 180

28x -2 = 180

28x = 182

x = 6.5

Answer:

x = 6.5

Step-by-step explanation:

The sum of the angles of a triangle is 180

8x+ 10x-10 + 10x +8 = 180

Combine like terms

28x -2 = 180

Add 2 to each side

28x-2+2 = 180+2

28x=182

Divide by 28

28x/28 = 182/28

x =6.5

The LATERAL Surface Area for the shape below is ____________. (assume the bases are the larger faces on the top and bottom.)
Zolol [24]

Answer:

LA=210\ cm^2

Step-by-step explanation:

we know that

The lateral area of the figure is given by

LA=Ph

where

P is the perimeter of the base (larger faces)

h is the height

Find the perimeter of the base P

P=2(11+10)=42\ cm

we have

h=5\ cm

substitute in the formula of lateral area

LA=42(5)=210\ cm^2

Find the area of this circle
IRISSAK [1]

Answer:

78.5398 cm^2

Step-by-step explanation:

r = 1/2*d => d = 10 cm

r = 5

A = pi*r^2

= pi*5^2 => 3.1415*5^2

=> 78.5398

Solve the following equations enter x-coordinate of the solution round to the nearest tenth
zalisa [80]
5y + 2y = 22 
(add 2y to 5y)
7y = 22
(divide each side by 7)
y ≈ 3.1

-2y + 6y = 3
(add 6y to -2y)
4y = 3
(divide each side by 4)
y = 0.75

Write the slope-intercept form of the equation for the line.
OLEGan [10]

let's use those two endpoints in the line of (-5 , 2) and (5 , -1)

\bf (\stackrel{x_1}{-5}~,~\stackrel{y_1}{2})\qquad (\stackrel{x_2}{5}~,~\stackrel{y_2}{-1}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-1-2}{5-(-5)}\implies \cfrac{-3}{5+5}\implies -\cfrac{3}{10}

\bf \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-2=-\cfrac{3}{10}[x-(-5)]\implies y-2=-\cfrac{3}{10}(x+5) \\\\\\ y-2=-\cfrac{3}{10}x-\cfrac{3}{2}\implies y=-\cfrac{3}{10}x-\cfrac{3}{2}+2\implies y=-\cfrac{3}{10}x+\cfrac{1}{2}
