3420°
Step-by-step explanation:
The sum of angle measures of an n-gon is ...
angle total = (n-2)×180°

Answer:
JF=45
KGH=62
Step-by-step explanation:
since the quadrilateral is a rhombus, its sides are equal GF=FJ and so on
Diagonals of a rhombus bisect each other at 90° angles, to find the missing value we subtract 90+28(the given angle) to get 62
X = 14
1/2 of 14 = 7
7 + 13 = 20
The first 1 is 42.5%
2nd 1 is 21
