Question

Sin alpha=1/2 and cos beta=1/2 then find the value of (alpha+beta)

Answer 1

Answer:

Step-by-step explanation:

Answer 2

The value of $\alpha+\beta= 90^{\circ}$

Step-by-step explanation:

$Sin \alpha = \frac{1}{2}$

$\alpha = Sin^{-1}(\frac{1}{2})$

$\alpha = 30^{\circ}$

$Cos \beta = \frac{1}{2}$

$\beta = Cos^{-1}(\frac{1}{2})$

$\beta = 60^{\circ}$

$\alpha+\beta= 30^{\circ}+60^{\circ}$

$\alpha+\beta= 90^{\circ}$

Hence The value of $\alpha+\beta= 90^{\circ}$
