Answer:

x=12

Step-by-step explanation:

Do 2 multiplied by x to get 2x, then do 2*1 to get 2.  You then add 2 to each side to balance out the -2 on the left.  You then subtract 1x from each side to get rid of the x on the right.  This leaves you with x=12

2x-2=x+10

2x=x+12

x=12

Find the measure of each interior angle
diamong [38]
\bf \textit{sum of all interior angles of a polygon}\\\\
180(n-2)\quad 
\begin{cases}
n=\textit{number of sides}\\
---------\\
n=10
\end{cases}\implies 180(10-2)\implies 1440\\\\
-------------------------------\\\\
\begin{array}{lclll}
&x + 5\\&x + 10\\&x + 20\\&x + 30\\&x + 35\\&x + 40\\&x + 60\\&x + 70\\&x + 80\\+&x + 90\\
&----\\
&10x+440
\end{array}\implies 
\begin{array}{llll}
10x+440=1440
\\\\\\
10x=1000
\\\\\\
x=\cfrac{1000}{10}\implies x=100
\end{array}

so.. to get every angle, simply plug in 10 for "x" for each.

Please help! I can't find any tutorial videos
Lena [83]

The two horizontal lines are parallel ( This is given by the red triangles)


Because the lines are parallel, the two angles 1 & 2 would be the same.

Set the two equations for the angle to equal each other and solve:

8y-6 = 7y

Add 6 to each side:

8y = 7y+6

Subtract 7y from each side:

y = 6

Now you have the value for y, solve for angle 2 by replacing y with 6:

Angle 2 = 7y = 7(6) = 42 degrees.
