Question

find value of alfa and beta if sin 80°+sin 50°=2 sin alpha × cos beta​

Answer 1

O don’t know sorry

Plsss
Forgive me

Answer 2

Answer:

alpha= 65 beta=15

Step-by-step explanation:

sin 80°+sin 50°=2sin(80+50/2). cos(80-50/2)

= 2sin(130/2). cos(30/2)

= 2sin(65). cos(15)

=2sin alpha.cos beta

alpha= 65, beta=15
