Im seriously in need of help anybody im not joking around please

A.) = 6

If RE = 12, then RD = 6

B.) = 10

If BR = 10, then BE = 10

C.) = 16

If BD = 8, then BK = 16

D.) = 30*

<m9 = 90*, and <m2 = 60*, so add them and subtract from 180*, you are left with <m1 = 30*

E.) = 60*

If <m2 = 60*, then <m3 = 60*

F.) = 90*

It`s a 90* angle because BK and RE and perpendicular

G.) = 60*

If <m1 = 30*, then multiply by two because it is symmetrical

I would show all my work but you seem to be in a rush. Hope this helps!

i those same problems in math and dont know how to do them
