Answer:

see explanation

Explanation:

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the given angles from 180 for B

B = 180° - (90 + 43)° = 180° - 133° = 47°

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

tan43° =
(opposite)/(adjacent) =
(23)/(b)

Multiply both sides by b

b × tan43° = 23 ( divide both sides by tan43° )

b =
(23)/(tan43) ≈ 24.7 ( to the nearest tenth )

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

sin43° =
(opposite)/(hypotenuse) =
(23)/(c)

Multiply both sides by c

c × sin43° = 23 ( divide both sides by sin43° )

c =
(23)/(sin43) ≈ 33.7 ( to the nearest tenth )
