Given:
Triangle EFG and EHG are two right triangles.


To find:
The values of x and y.
Solution:
In triangle EFG,
[Angle sum property]





In triangle EHG,
[Angle sum property]





Therefore, the value of x is 25 and the value of y is also 25.
The answer is 66610 becausse it 10 time bigger
X= adults
y=children
x+y=20
x=20-y
18x+12y=324
18(20-y)+12y=324
360-18y+12y=324
-6y=324-360
-6y=-36
y=-36/-6
y=6
x=20-y
x=20-6
x=14
