The length of WX of the trapezium is: 29
How to find the length of the Trapezium?
We are given the parameters as:
ST = 10x + 5
WX = 7x + 8
UV = 8x - 1
Since SW = UW, then WX is centered between UV and ST
Thus:
(10x + 5) - (7x + 8) = (7x + 8) - (8x - 1)
3x - 3 = -x + 9
4x = -12
x = 3
substitute
WX = 7(3) + 8
WX = 29
Complete question is:
Find WX, ST = 10x + 5, WX = 7x + 8, UV = 8x - 1
