Answer:

h ≈ 13.4

Step-by-step explanation:

Since the triangle is right we can use the sine ratio to find h

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

Multiply both sides by 18

18 × sin48° = h

⇒ h = 13.4 cm ( to 1 dec. place )

3. a^9+16

here 16 is not a perfect cube.

4. a^16+8

(a^4)^3+2^3

Thus, is a sum of cubes.
