Question

P
8X ABCD is a cyclic quadrilateral. If m/_BAD= 35º, what is m/_BCD?
(1) 35° (2) 70° (3) 145° (4) 60°​

Answer 1

Step-by-step explanation:

A cyclic quadrilateral is a quadrilateral which has all its four vertices lying on a circle.

The sum of two opposite angles in a cyclic quadrilateral is equal to 180 degrees (supplementary angles)

when we draw the figure a and c are opposite vertices

so a+ c= 180

given a= 35

measure of angle bcd=180-35= 145°

Answer 2

Answer:

since the sum of opposite angles of a cyclic quadrilateral are supplementary

angle BAD+ angle BCD= 180°

35°+ angle BCD= 180°

angle BCD= 180-35

angle BCD= 145°

Answer:-

$c)145$
