Question

in the given figure, points A. B. C and D lie on a circle. BC
is produced to P and ZBAD = 100°. The measure of ZDCP
(a) 100
(c) 110
(890​

Answer 1

Answer:

100

Step-by-step explanation:

ABCD Is definitely a cyclic quad.

ext. angle of a cyclic quad.= angle measurement of the opp. vertex.= 100°

Answer 2

Step-by-step explanation:

We know that opposite angles of a cyclic quadrilateral are equal to 180.

$a \: + \: c \: = 180$

100 + C = 180

C = 80

Now

• DCB + DCP = 180
• 80 + DCP = 180
• DCP = 100
