Question

87. In the following figure, CB is produced to the
point A. Find angle BDC.
plz solve this question ​

Answer 1

Answer:

hey there im also solving this particular question from the same book you have i think the answer is 40 degrees probably cause of alternate angles.

Step-by-step explanation:

to cement my answer here is the probable proof -

angle ebd is equal to angle bdc cause of alternate angles

and since angleb is bisected the 80 degrees should be halved into 40 degrees.

if any mistake or clarification comment and i will try and answer it ASAP.

Answer 2

Answer:

40

Step-by-step explanation:

EBC = 180-100 = 80

bec = 180-(60+80) = 40

bec = BDC = 40 since angles in the same segment are equal
