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

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 )

Solve: -25 < x + 20 < 25
denis23 [38]

Answer:

-45 < x < 5 (see graph below)

Step-by-step explanation:

to isolate x by itself, subtract 20 from all three terms of the equation:

(-25-20)

once you finish subtracting 20, x should be by itself, making the equation graphable:

-45 < x < 5

since x is not equal to -45 or 25, the graph line endings have open circles.
