Solving the right triangle (round to the nearest tenth)

see explanation

Step-by-step 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° = =

Multiply both sides by b

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

b = ≈ 24.7 ( to the nearest tenth )

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

sin43° = =

Multiply both sides by c

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

c = ≈ 33.7 ( to the nearest tenth )
