Answer:
112
Step-by-step explanation:
I took the same test
area of trapezium = <u>a</u><u>+</u><u>b</u><u> </u>×h (a+b = base +base )
2
38+18÷2×16
37×16
Since AD bisects BC,
BD = DC.
Therefore 5x - 10 = 3x + 10 and x = 10.
-6x - 2y = -18
-6x - 2(0) = -18
-6x - 0 = -18
-6x = -18
-6 -6
x = 3
hope this helps :)
