Step-by-step explanation:

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

Subtract the sum of the given angles from 180 for A

A = 180° - (90 + 46)° = 180° - 136° = 44°

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

tan46° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{b}{23}[/tex]

Multiply both sides by 23

23 × tan46° = b, thus

b ≈ 23.8 ( to the nearest tenth )

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

cos46° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{23}{c}[/tex]

Multiply both sides by c

c × cos46° = 23 ( divide both sides by cos46° )

c = [tex]\frac{23}{cos46}[/tex] ≈ 33.1 ( to the nearest tenth )
