Answer:
≈ -0.0005
Step-by-step explanation:
Answer:
- Draw a line segment AB = 5.5 cm » Take A as a center and draw an
angle of 45°
- Take D as a center with radius
4.5 cm and draw an arc.
- Take B as a center with radius 3.5 cm and draw an arc, which
meets previous arc at point c.
therefore ABCD is a required quadrilateral.
Step-by-step explanation:
- the number being divided
- the number of parts that the dividend is being divided into
- opposite equations that undo one another
- the result of dividing two numbers
For a problem of this nature, we need to assume that the base of the observation tower is at the same elevation as the fire. The tangent of the angle is the ratio of tower height to horizontal distance:
tan(α) = (tower height)/(horizontal distance)
Rearranging this equation, we have
(horizontal distance) = (tower height)/tan(α)
Putting in the given values gives
(horizontal distance) = (90 ft)/tan(7°) ≈ 733 ft
