How do i find x?

Answer:
<h3> To find x you need to divide polygon into triangles</h3><h3>The formula : "the sum of exterior angles=360°" is false for concaved polygons</h3>Step-by-step explanation:
α = 180° - 135° = 45°
β = 180° - 120° = 60°
γ = 180° - 60° = 120°
δ = 180° - x
ε = 180° - 80° = 100°
If we divide the pentagon into five triangles then:
5•180° = α + β + γ + δ + ε + 4x
900° = 45° + 60° + 120° + x + 100° + 4x
900° = 325° + 5x
5x = 575°
x = 115°
60° + 120° + 135° + 80° + 115° = 510° ≠ 360°

Answer:
-23,
Step-by-step explanation:
We need slope intercept form but do not have the needed information. We will gather this information by using point slope form. The point-slope formula is where we substitute a point (x,y) for
.
We have slope represented as m=6 and (3, -5). We input m and .
We now simplify the parenthesis and solve for y to have slope intercept form.
The y-intercept is b of slope intercept form y=mx+b. Here b=-23.
