Answer: 5
Explanation:
Given : In the the given kite , we have
TU= 15x-23 and UV = 3x+37
A kite has two pairs of consecutive sides that are equal in length.
In the given figure , we have TU and UV are adjacent shorter sides in the kite , which must be equal.
Then , we have the following equation :-

Hence, the value of x= 5
