Question

In a cyclic quadrilateral two
adjacent angles are 40' and
(π÷3©) find the angles of the
quadrilateral in degree




plzz sol.this que. I will definitely mark as a brainlist​

Answer 1

Answer:

120 and 140

Step-by-step explanation:

π÷3©=60©

we know opposite angles of cyclic quadrilateral are supplementary

so, 40+angle1=180

angle1=140

also, 60+angle2=180

angle2=120

Answer 2

Step-by-step explanation:

GIVEN : angle a =40 and angle b=60

we know sum of cyclic quardilateral are supplementary

angle a+angle c=180 degree

angle b+angle d=180 degree

now,

angle a+angle c = 180 degree

40degree+angle c=180 degree

angle c= (180-40) degree

angle c=140 degree

next

angle b+angle d=180 degree

60 degree + angle d=180 degree

angle d=(180-60)degree

angle d=120 degree

so

angle a=40 degree

angle b=60 degree

angle c=140 degree

angle d=120 degree

i hope so that it will be very useful for u all
