Question

Yadi sinA=1/2 or cosB=1/2 Diya ho to (A+B) ka maan Kya hoga

Answer 1

Answer:

sinA = 1/2 (i)

cosB = 1/2 (ii)

from (i) and (ii)

sinA = cosB

cos ( 90 - A ) = cosB

90 - A = B

therefore, A + B = 90

I hope this may helpful for u

Answer 2

Step-by-step explanation:

we know that,

when sin theta= 1/2

then , theta = 30

when cos theta= 1/2

then , theta = 60

so, now we have

sinA=30

cosB=60

so,(A+B)=

30+60=

90

Thanks.
