Answer:

x =
√(6) , y = 2
√(3)

Explanation:

using the tangent ratio and the exact value tan45° = 1 , then

tan45° =
(opposite)/(adjacent) =
(x)/(√(6) ) = 1 , then

x =
√(6)

----------------------------------

using the cosine ratio in the right triangle and the exact value

cos45° =
(1)/(√(2) ) , then

cos45° =
(adjacent)/(hypotenuse) =
(√(6) )/(y) =
(1)/(√(2) ) ( cross- multiply )

y =
√(6) ×
√(2) =
√(12) = 2
√(3)
