@campbell_st help plzz

Answer 5

well angle BCD = 90 there is a circle geometry postulate about the angle in a semicircle is a right angle

and if arc CB is 36 then angle CDB = 36

so you can use angle sum of a triangle to find your required angle.

Answer 6

how to do it ?!?!

Answer 7

well its

180 - 90 - 36 = angle DBC

Answer 8

DBC=54
