First we would need to make a diagram, and from the given it would seem like it is a right triangle with the height as 760 ft. We have an angle given 89°18' which would need to be converted to degrees form, which is 89.3<span>°. 

Now we would need to look for the ground distance, meaning the adjacent of the triangle. Since we have been given the angle and the height (which is the opposite side from the angle) we use the trigonometric function cotangent.

</span><span>760 Cot <span>[<span><span>(<span>89.3</span>)</span>∘</span>]</span>= 9.29 ft, that is the answer.</span>

Answer:

The headquarters is 9 ft away from a point on the ground directly below the balloon .

Step-by-step explanation:

The height of balloon is 760 ft and the angle of depression is 89°18' = 89 \frac{18}{60} =89.3°.

A right angled triangle is formed ( as shown in figure ) .Let x represent the distance of headquarters from a point on the ground directly below the balloon .

Tan 89.3=\frac{760}{x}

81.85 x= 760 .[ Tan 89.3= 81.85]

Dividing both sides by 81.85:

x= 9.3

Or x=9 ft ( rounded to nearest foot)

The headquarters is 9 ft away from a point on the ground directly below the balloon .

8/20 greater than or less than 2/10
kumpel [21]
8/20 is greater than 2/10. If you were to make the denominators the same, by mulipling 2x2 and 10x2, you would get 4/20, which is less than 8/20.

Answer:

  • <em><u>5.6875 in</u></em>

Explanation:

At the point of tangency, the <em>tangent </em>to a circle and the <em>radius</em> form a right triangle (the radius is perpendicular to the tangent).

Here you are given the length of the tangent (6in), and the distance from the bisected vertex to the circle (2.75 in)

I tried to upload the drawing but the tool is not allowing it now.

In the figure:

  • The length of the tangent (6 in) is one leg of the triangle
  • The distance from vertex and the circle (2.75in)  along with the radius forms the hypotenuse of the right triangle: 2.75 + r.
  • The other leg is the radius, r.

Then, you can use Pythagorean theorem:

  • (r)² + (6)² = (r +2.75)²

Solve:

  • r² + 36 =  r² + 5.5r + 7.5625
  • 5.5r = 36 - 7.5625
  • 5.5r = 28.4375
  • r = 5.6875

The solution is in inches: r = 5.6875 inches ← answer
