If °m<cda=44, what is mcba?

Answer 11

m<cba*

Answer 12

i dont see that as answer

Answer 13

for the first q, since R = 37, O would be twice of that

O = 2R
= 2x 37
= 74

Answer 14

@coe

Answer 15

yh

Answer 16

for the 2nd q, look at the pic

Answer 17

i got it it was 44

Answer 18

both CDA and CBA are inscribed angles of same arc CA. so they are congruent

Answer 19

CDA = CBA

Answer 20

does that make some sense

Answer 21

yes it does! i have some more could you help

Answer 22

sure post them il see if i can :)

Answer 23

okayy :)

Answer 24

Find the measure of BAC. The figure is not drawn to scale.

Answer 25

look at the pic. we knw O = 54, we need to find A

Answer 26

see that O and A are eating the same arc BC

Answer 27

yea

Answer 28

A is called inscribed angle, O is called cetral angle

Answer 29

there is a relation between the two

Answer 30

inscribed angle = central angle /2

Answer 31

A = O/2
= 54/2
= ?

Answer 32

ohhh 27!

Answer 33

yes!

Answer 34

yayyy

Answer 35

Given that DAB and DCB are right angles and mBDC = 46º, what is cad?

Answer 36

look at triangle BDC

Answer 37

can you tell me all its 3 angles

Answer 38

two are given already. just find the 3rd angle, and tell me all 3 angles

Answer 39

two are 90 and one is 46

Answer 40

no, try again. i want you look at triangle BDC and tell me its angles.

Answer 41

and what you said above is wrong cuz, a triangle can never have more than one angle with 90.

Answer 42

ummmm angle a b c and d?
