Answer:
X + Y - W - Z = 180
Step-by-step explanation:
In parallel lines If you use the rules of:
* Alternate angles are equal
* Linear Pair Angles supplement to 180
And use the picture below for calculating the result: finally we get
Z = Y - (180 - (X - W)) which becomes the answer above if you simplify the parentheses.
11. Area as product = 7( d + 4 )
Area as sum = 7d + 28
12. Area as product = y( y + 3 )
Area as sum = y^2 + 3y
13. In circles , 12x and 60
Area as product = 12 ( x + 5 )
Area as sum = 12x + 60
14. In circles , x and 4
Area as product = 5 ( x + 4 )
Area as sum = 5x + 20
Hope this helps :)
