Thank you for the opportunity to help you with your question!

1. Given in diagram,

HK = 39   and  JK = 9

Now,

HJ + JK = HK

or, HJ = HK- JK

HJ = 39-9 = 30

..............................................................

4. Given in diagram,

EF = 6x-4, FG = 3x and EG = 5x+8

Now,

EF + FG = EG

or, 6x-4 + 3x = 5x+8

or, 9x-5x = 8+4

4x = 12

x = 3

therefore,

EF = 6x-4 = (6X3)-4 = 14

FG = 3x3 = 9

EG = (5x3)+8 = 23
