Answer:

Option A) angle bisector

Step-by-step explanation:

Angle Bisector:

An angle bisector is a line that divides an angle into two equal parts.
The angle bisector divide the angle in two equal parts.
An angle bisector is equidistant from the sides of the angle when measured along a segment perpendicular to the sides of the angle.
It cuts the angle into half.
Thus, a sector can be divided into two equal sectors by drawing an angle bisector.

To divide the sector into two congruent sectors we can use the angle bisector construction.

ruslelena [56]

Answer:

0.3

Step-by-step explanation:

Given:

Number of small dogs = 18

Number of medium-sized dogs = 12

Number of large dogs = 10

To find: probability that a medium-sized dog will be chosen

Solution:

Probability refers to chances of occurrence of some event.

Probability = number of favourable outcomes/total number of outcomes

Total number of dogs = 18 + 12 + 10 = 40

Number of medium-sized dogs = 12

So,

probability that a medium-sized dog will be chosen = Number of medium-sized dogs/Total number of dogs = $\frac{12}{40}=0.3$
