The diagram shows a scale drawing of a lacrosse field. The diagram is 5 1/2 inches long and 3 inches wide. If 1 inch represents
Elan Coil [88]

Answer:

  6600 yd²

Step-by-step explanation:

The area of the scale drawing is ...

  (5.5 in)(3 in) = 16.5 in²

Each square inch represents an area of the field that is ...

  (20 yd)×(20 yd) = 400 yd² . . . . per square inch of drawing

Then the scale drawing represents a field with an area of ...

  (16.5 in²)×(400 yd²/in²) = 6600 yd²

Find the value of b.
Nesterboy [21]

Answer: 230^{\circ

Step-by-step explanation:

For convenience, I labeled some points as shown in the attached picture.

Also, I assume \overline{AB} and \overline{BC} are tangents to the circle.

  1. \overline{BO} \cong \overline{BO} (reflexive property)
  2. \overline{AB} \cong \overline{BC} (tangents drawn from a common external point are congruent)
  3. \angle BAO \cong \angle BCO (right angles are congruent)

Therefore, we know \triangle ABO \cong \triangle CBO by HL.

Thus, by CPCTC,

\angle AOB \cong \angle BOC \implies m\angle BOC=65^{\circ}\\\\\implies m\angle AOC=130^{\circ}

This means the measure of minor arc AC is 130^{\circ}, and thus b=360^{\circ}-130^{\circ}=\boxed{230^{\circ}}
