Answer:
∠ 4 = 140°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ 4 is an exterior angle of the triangle, then
∠ 4 = ∠ 1 + ∠ 2 ( substitute values )
11x + 8 = 6x + 7 + 4x + 13
11x + 8 = 10x + 20 ( subtract 10x from both sides )
x + 8 = 20 ( subtract 8 from both sides )
x = 12
Then
∠ 4 = 11x + 8 = 11(12) + 8 = 132 + 8 = 140°
I hope this helps!
Apologies that the photo of the actual notebook is a little small, trying to handle this app’s photo-taking capabilities is a little weird for me.

It's three fourths, she ate one fourth.
A polygon<span> has as many interior </span>angles<span> as sides. An equilateral triangle has three equal 60 </span>degree angles<span>. The </span>sum<span> of the </span>angles<span> of this and any triangle is </span>180 degrees<span>.The </span>sum<span> of the four interior </span>angles<span> of a square is 360 </span>degrees<span>, which is the same for any quadrilateral.</span>
