Since W and V and X and U are congruent, or symmetrical to eachother, they equal eachother. 7 is x+1. So, x=6.
55-90=35 theres your answer... its suspicious they give easy answers in middle school u sure thats the question?
Answer:
x = 7/
or 4.949747468
Step-by-step explanation:
45-45-90 triangles have a specific pattern.
The smaller sides are x, & the hypotenuse is 
With this knowledge, we know we have to divide the hypotenuse by
to get the smaller sides, so we divide 7 by the
to find x.
