Question

if sin0⁰ sinx⁰,sin90⁰ are consecutive terms of AP then find x



​

Answer 1

Answer:

Step-by-step explanation:

sin0=0

sin90=1

0,sinx,1

a2-a1=a3-a2

sinx-0=1-sinx

2sinx=1

sinx=1/2                              (sin30=1/2)

x=30

Answer 2

It is given that sin0, sinx, sin90 are in ap

0 < sinx < 1

a2 - a1 = a3 - a2

sinx - 0 = 1 - sinx

2sinx = 1

sinx = 1/2

sin30 = 1/2

So, x = 30 degrees
