Answer:
x = 19°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles, thus
x + 106° = 125° ( subtract 106° from both sides )
x = 19°
They are similar, but I don't exactly know why. It has something to do with the angles, I know that.

Answer:
![\large\boxed{y=\dfrac{2}{3}x+1}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7By%3D%5Cdfrac%7B2%7D%7B3%7Dx%2B1%7D)
Step-by-step explanation:
The slope-intercept form of an equation of a line:
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept → (0, </em><em>b</em><em>)</em>
<em />
The fromual of a slope:
![m=\dfrac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
<em>(x₁, y₁), (x₂, y₂)</em><em> - points on a line</em>
<em />
We have the points from the graph:
(0, 1) → <em>b = 1</em> and (3, 3).
Calculate the slope:
![m=\dfrac{3-1}{3-0}=\dfrac{2}{3}](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7B3-1%7D%7B3-0%7D%3D%5Cdfrac%7B2%7D%7B3%7D)
Finally we have the equation of a line:
![y=\dfrac{2}{3}x+1](https://tex.z-dn.net/?f=y%3D%5Cdfrac%7B2%7D%7B3%7Dx%2B1)
