Question

if cos x = 1/2 and sin y = 1/2 find x+y​

Answer 1

Answer:

$\large{ \bold{ \cos(x) = \frac{1}{2} }}$

$\large{ \bold{ \cos(x) = \cos(60) }}$

$\large{ \bold{x = 60}}$

$\large{ \bold{ \sin(y) = \frac{1}{2} }}$

$\large{ \bold{ \sin(y) = \sin(30) }}$

$\large{ \bold{y = 30}}$

$\large{ \bold{ \purple{x + y = 90}}}$

Answer 2

Answer:

cos–1(1/2)+sin–1(1/2)

π/3+π/6

2π+π/6

3π/6

π/2
