Answer:

BC = 17
√(2) ft

Explanation:

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

sin45° =
(1)/(√(2) ) , then

sin45° =
(opposite)/(hypotenuse) =
(AC)/(BC) =
(17)/(BC) =
(1)/(√(2) ) ( cross- multiply )

BC = 17
√(2) ft

Answer:


17√(2) ft

Explanation:

take angle b as reference angle

using sin rule

sin 45 = opposite / hypotenuse


(1)/(√(2) ) = 17 / BC

BC =17 /
(1)/(√(2) )

BC = 17 *
√(2)

BC =
17√(2) ft
