Answer 1

Answer:

$\frac{x}{ac} = \cos(60) \\ x = 10 \cos(60) = 10 \times \frac{1}{2} = 5$

$\sin(y) = \frac{x}{bc} = \frac{5}{5 \sqrt{2} } = \frac{1}{ \sqrt{2} } \\ so \: \: y = \frac{\pi}{4}$

Answer 2

solution

cos60°=X/10

=>X=10×cos60°=10×0.5=5

and....

sinY=5/5√2

=>sinY=1/√2=sin45°

=>Y=45°
