Answer 1

help please, just copy and paste to see the picture

Answer 2

is triangle BCD 9 And 16 or 3 and 16, the picture is unclear?

Answer 3

The smaller angle at B is 38 degrees(call it k), due to sum of opposite interior angles is equal to exterior angle.

therefore: 90 + k = 128 => k = 38

Answer 4

so whats 1-6

Answer 5

part 2) angle ADB is 14 degrees, call it m

sum of interior angles must equal to 180

therefore 90+76+m=180 => m = 14

Answer 6

part 3) angle bdc is 52 degrees(call it p)

this can be noted by angles of a straight line must equal 180
therefore 128+p=180 => p=52 degrees

Answer 7

are you following?

Answer 8

no not really

Answer 9

i don't know how to explain this better?

Answer 10

what is the answer for
M<b=

Answer 11

do you know your rules of geometry?

Answer 12

what level are you at?

Answer 13

38, my second post in this thread

Answer 14

angle abd=76 right?
angle cbd=38
angle cab is 114

so depends on which b you looking for?

Answer 15

what is cd

Answer 16

ad and ba
