Quadrilateral WXZY is a square. If YX = 30 and WT = 2x – 7, then find the value of x.

Question

geerky42 · Answer

Since it is square, all sides are the same so YX = WT, therefore 30 = 2x - 7. Solve for x.

campbell_st · Answer

that doesn't work as there is no T as a vertex of the square...

If you have a diagram with your question can you post it

I see. I didn't notice it, so this problem don't give enough given information. Please post the diagram just like @campbell_st said if you have it.

campbell_st · Answer

the 4 vertices of the square are WXZY    where is T...? thats why you can't say 30 = 2x - 7

I think the answer would be 18.5? Not sure though

campbell_st · Answer

ok the diagonals of a square are equal in length and bisect each other. so you can say 

a half of XY = 15

so then XT = WT 

or 15 = 2x - 7

solve for x
