[tex]Answer: \\ \cos(47°) = \frac{h}{12} \\ \Leftrightarrow h = 12\cos(47°) \approx8.2[/tex]

Answer:

h ≈ 8.2

Step-by-step explanation:

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

cos47° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{h}{12}[/tex]

Multiply both sides by 12

12 × cos47° = h

⇒ h = 8.2 cm ( 1 dec. place )
