Question

I need help it is overdue ): ​

Answer 1

x = 4
`√(3)` , y = 4

Explanation:

using the cosine and sine ratios in the right triangle and the exact values

cos30° =
`(√(3) )/(2)` , sin30° =
`(1)/(2)` , then

cos30° =
`(adjacent)/(hypotenuse)` =
`(x)/(8)` =
`(√(3) )/(2)` ( cross- multiply )

2x = 8
`√(3)` ( divide both sides by 2 )

x = 4
`√(3)`

and

sin30° =
`(opposite)/(hypotenuse)` =
`(y)/(8)` =
`(1)/(2)` ( cross- multiply )

2y = 8 ( divide both sides by 2 )

y = 4
