Question

Geometry math question

Answer 1

we know that KUCN=105

CN=51

HMKU=96

HM=HMKU-MKU=96-78=18

we know that JN=JK+KN=82+105=187

JN=JH+HM+MKU+UC+CN

187=22+18+78+UC+51

UC=18.

Answer 2

the difference between 96 and 78 is 18 which is the length of HM which is equal to UC therefore making UC 18 as well.
