Answer:

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 A

A = 180° - (90 + 48)° = 180° - 138° = 42°

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

tan48° = $\frac{opposite}{adjacent}$ = $\frac{18}{a}$

Multiply both sides by a

a × tan48° = 18 ( divide both sides by tan48° )

a = $\frac{18}{tan48}$ ≈ 16.2 ( to the nearest tenth )

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

sin48° = $\frac{opposite}{hypotenuse}$ = $\frac{18}{c}$

Multiply both sides by c

c × sin48° = 18 ( divide both sides by sin48° )

c = $\frac{18}{sin48}$ ≈ 24.2 ( to the nearest tenth )
