Question

Solve for x and y...............​

Answer 1

9 for x..................

Answer 2

9.
`x=30, y=10√(3)`

11.
`x=5√(3), y=10√(3)`

Explanation:

9)

`\sin x=(10)/(20)\\x=\sin^(-1)\left( (1)/(2) \right)=30^(\circ)\\y=√(20^2-10^2)=√(400-100)=√(300)=10√(3)`

11)

`\tan 60= (15)/(x)\\x=(15)/(\tan 60)=5√(3)\\y=\sqrt{(5√(3))^2+15^2}=√(75+225)=√(300)=10√(3)`

Hope this helps!
