Answer:

I can help with Q "4" as -

It uses triangle congruence test - here we use - SAS, as

one side is equal as it is given

both the angles are 90 degree

and they share a same side

so -

8x = 6x + 5

8x - 6x = 5

2x = 5

x = 2.5

RU = 6x+ 5 = 6 (2.5) + 5 = 20

( I am not so sure but I think this is the answer )
