what is the value of Y?

Answer:
Step-by-step explanation:
Your first job is to get TU = UV
US = US Reflexive property
VS = ST The lengths of both are 45
TV is a straight line with 2 right angles. If a straight line has 1 triangle on it then it has two
ΔTSU = ΔVSU SAS
VU = UT Corresponding parts of congruent triangles are =
5y = y + 48 Subtract y from both sides
5y-y = 48 Combine
4y = 48 Divide by 4
4y/y = 48/4
Answer: y = 12
