Question

ANS KIYA HOGA












????¿????????​

Answer 1

Answer:

sina = 1/2

$\sin( \alpha ) = \frac{1}{2}$

$( \alpha ) = 30 {}^{0}$

$\cos( \beta ) = \frac{1}{2}$

$\beta = 60 {}^{0}$

$\alpha + \beta = 30 + 60 = 90 {}^{0}$

90⁰ is answer

follow me on brainly

Answer 2

Answer:

sina = 1/2

\sin( \alpha ) = \frac{1}{2}sin(α)=21

( \alpha ) = 30 {}^{0}(α)=300

\cos( \beta ) = \frac{1}{2}cos(β)=21

\beta = 60 {}^{0}β=600

\alpha + \beta = 30 + 60 = 90 {}^{0}α+β=30+60=900

ans= 90
