I dont get any of this stuff

Answer 1

Answer:

x = 19, y = 19$\sqrt{3}$

Step-by-step explanation:

Since the triangle is right, we can use the sine and cosine ratios to find x and y

note the exact values of cos60° = $\frac{1}{2}$ and

sin60° = $\frac{\sqrt{3} }{2}$

cos60° = $\frac{adjacent}{hypotenuse}$ = $\frac{x}{38}$

multiply both sides by 38

x = 38 × cos60° = 38 × $\frac{1}{2}$ = 19

sin60° = $\frac{opposite}{hypotenuse}$ = $\frac{y}{38}$

multiply both sides by 38

y = 38 × sin60° = 38 × $\frac{\sqrt{3} }{2}$ = 19$\sqrt{3}$
