Question

Abcd is cyclic quadrilateral and sin A=3/5 ,then sin C

Answer 1

Step-by-step explanation:

since abcd is cyclic quadrilateral

angle a+angle c=180

value of sin 180 =0

sinA+sinC=sin180

3/5+sinC=0

sinC=0

Answer 2

Answer:

sin C = 3/5

Step-by-step explanation:

In a cyclic quadrilateral

sum of opposite angles = 180°

so, A + C = 180°

C = 180° - A

Now,

sin C = sin (180° - A)

sin C = sin (180° - A)

[ using trigonometric identity, sin (180° - x) = sin x]

sin C = sin A

sin C = 3/5
