Question

How do I find the answer for this?

Answer 1

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.
