This is Trigonometry​

Answer 1

x = 20.41 units, y = 11.71 units to the nearest hundredth.

Explanation:

Consider the small triangle:

cos 20 = 11/y

y = 11 / cos 20

= 11.706 units.

Now the larger triangle:

sin 35 = 11.706 / x

x = 11.706 / sin 35

x = 20.409 units.

Answer 2

x ≈ 20.42, y ≈ 11.71

Explanation:

Using the cosine ratio on the right triangle on the right, that is

cos20° =
`(adjacent)/(hypotenuse)` =
`(11)/(y)`

Multiply both sides by y

y × cos20° = 11 ( divide both sides by cos20° )

y =
`(11)/(cos20)` ≈ 11.71

Using the sine ratio on the right triangle on the left, that is

sin35° =
`(opposite)/(hypotenuse)` =
`(y)/(x)` =
`(11.71)/(x)`

Multiply both sides by x

x × sin35° = 11.71 ( divide both sides by sin35° )

x =
`(11.71)/(sin35)` ≈ 20.42
