Answer:
x=16
y= 100
Step-by-step explanation:
<1 and <3 are vertical angles so they are equal
5x = 80
Divide each side by 5
5x/5 = 80/5
x = 16
Angles 2 and 3 are supplementary since they form a straight line, they will add to 180
<2 + <3= 180
y+80 = 180
Subtract 80 from each side
y+80-80 = 180-80
y= 100
