Question

if sin alpha = cos beata, then what is the value of alpha + beata​

Answer 1

Given, sinx = cosy , then x+y=?

sinx = cosy

sinx =sin(90-y) (because sin(90-X) =cosX)

=> x = 90-y

x + y = 90

Answer 2

Answer:

90°

Explanation

sin alpha = 1/2

sin alpha = sin 30°

alpha = 30°

cos beata =1/2

cos beata = cos 60°

Beata = 60°

alpha + beata = 30° + 60

= 90°

Write the sign of alpha and beata instead of its spelling...!

hope it'll help you...
