Cos x = sin (90 - x)
cos 63 = sin (90 - 63)
cos 63 = sin 27
x = 27
Answer:
To begin solving we subtract 3 from each side
4w = -10
Next, we divide both side by 4
w = -2.5
~CoCo
X=7, y=3
because it is an algebraic method you have to solve for an x or y in either equation, and then plug that into the other equation. it’s helpful for these problems to check your work and plug the numbers back into the equations and the end for future reference !
