Answer:
The angles are 45°, 60° , 75°
Step-by-step explanation:
<h3>
Angle sum property:</h3>
Sum of all the angles of a triangle is 180°.
Equation:
3x + 5x + 4x = 180
Combine like terms,
12x = 180
x = 180/12

3x = 3 *15 = 45°
5x = 5* 15 = 75°
4x = 4 *15 = 60°
No of people not from their neighborhood=25-20=5
total contact s=25
therefore probability to call a person not from his neighborhood=5/25=1/5
therefore P=1/5
