Step-by-step explanation:
Answer:
x=20 and y=100
Step-by-step explanation:
Using vertical angles, angle 1 and 3 equal each other. Therefore, x=80/4. Then, by using the sum of angle 1 and 3, 160, and using vertical angles again, we can find angle 2, which is (360-160)/2.
So basically you need to multiply 3000x4000 in two ways? If so you can use basic multiplication and an area model
