Question

Help please On this problem

Answer 1

$Answer: \\ \cos(47°) = \frac{h}{12} \\ \Leftrightarrow h = 12\cos(47°) \approx8.2$

Answer 2

Answer:

h ≈ 8.2

Step-by-step explanation:

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

cos47° = $\frac{adjacent}{hypotenuse}$ = $\frac{h}{12}$

Multiply both sides by 12

12 × cos47° = h

⇒ h = 8.2 cm ( 1 dec. place )
