Answer:
Explained Below
Step-by-step explanation:
We know angles 1 and 3 are opposite angles, therefore they are the same angle. Using that we can make the first equation:
100 = 10x
divide both sides by 10.
x = 10
To find Y we know angles 3 and 2 are supplementary angles, meaning they add up to 180. Using that, we create the equation:
(10y + 20) + 100 = 180
Simplify.
10y + 20 = 80
10y = 60
y = 6
Your answers are 6 for y, 10 for x.
