Answer:

c = 7
√(3)

Explanation:

Using the sine ratio in the left right triangle and the exact value

sin45° =
(√(2) )/(2), then

sin45° =
(opposite)/(hypotenuse) =
(a)/(7√(2) ) =
(√(2) )/(2) ( cross- multiply )

2a = 14 ( divide both sides by 2 )

a = 7

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

Using the tangent ratio in the right triangle and the exact value

tan30° =
(1)/(√(3) ) , then

tan30° =
(opposite)/(adjacent) =
(a)/(c) =
(7)/(c) =
(1)/(√(3) ) ( cross- multiply )

c = 7
√(3)
