Answer:
undefined
Step-by-step explanation:
The x value does not change, which means it is a vertical line
Vertical lines have an undefined slope
we can check using
m = (y2-y1)/(x2-x1)
=(2- -2)/( -3 - -3)
= (2+2)/( -3+3)
4/0
undefined
First, find out x
x+15+2x+15=180
3x+30=180
3x=150
x=50
so the two angels are x+15=65(let's name is ∠5 for convenience), and ∠6= 2x+15=115
notice the two inner lines are marked as congruent, so
∠4=∠5=65
∠1=180-∠4-∠5=180-65-65=50
Name the right bottom angle ∠7, ∠3=∠7 and ∠3+∠7=the exterior angle 100 degree, therefore, ∠3=50
∠2+∠3=∠4, therefore, ∠2=∠4-∠3=65-50=15
∠1=50, ∠2=15, ∠3=50, ∠4=65
