Question

find angle ADC BCD ​

Answer 1

$\huge\bold\red{Hello mate}$

$<b>We know,opposite angles of a cyclic quadrilateral is always supplementary.</b>$

So,

ADC=180°-65°=$\boxed{115°}$

BCD=180°-75°=$\boxed{105°}$

Answer 2

Answer:

Step-by-step explanation:

first it is cyclic quad.

there fore sum of opposite angle = 180°

angle ADC + angle ABC = 180°

ANGLE ADC + 65 = 180°

ADC = 180 - 65 = 115°

lly for DCB+BAD = 180

  DCB + 75 = 180

DCB = 180 - 75

 = 105°

AND ALSO SUM OF ALL ANGLE OF QUAD = 360°

∴  75 + 65+ 105+115 = 360
