In the figure, AOB and COD are straight lines. Find x and y.

20

The image of the straight lines is missing so i have attached it.

x = 20°

y = 120°

Step-by-step explanation:

From the image attached, we can say that;

3x + (7x - 20) = 180

This is because sum of angles on a straight line is 180°

Thus;

3x + 7x - 20 = 180

10x = 180 + 20

10x = 200

x = 200/10

x = 20°

Also,3x + y = 180

Because sum of angles on a straight line is 180°. Thus;

3(20) + y = 180

60 + y = 180

y = 180 - 60

y = 120°

i'm pretty sure it's 477,585,296, but perhaps my math is incorrect.

step-by-step explanation: 6870

1857 times .63 equals 1169.91 subtract that from 1857 you get 687.09
