Answer:
Step-by-step explanation:
Diagonals intersect at 90
2z - 8 = 90
2z = 90 + 8
2z = 98
z = 98/2
z = 49
Adjacent sides are congruent
5x - 12 = 3x + 2
5x = 3x + 2 + 12
5x = 3x + 14
5x - 3x = 14
2x = 14
x = 14/2
x = 7
3x + 2 = 3*7 + 2
= 21 + 2
= 23
Use Pythagorean theorem to find y
16² + y² = 23³
256 + y² = 529
y² = 529 - 256 = 273
y = √273
y = 16.52
