Two straight lines of wire are placed on the ground forming vertical angles if the measure of one of the angles formed a 72° what are the measures of the other three angles

Respuesta :

The measures of angles are [tex] \bold{72^{\circ},108^{\circ} and 108^{\circ}} [/tex]

Solution:

The angles opposite to each other are equal.  

Angle 1 = Angle 3  

Angle 2 = Angle 4  

Given that one of the angle formed is [tex]72^{\circ}[/tex]

Consider Angle 1 = [tex]72^{\circ},[/tex]

Hence Angle 3 is also [tex]72^{\circ}[/tex]

Since the angle formed in a straight line is [tex]180^{\circ},[/tex]

Angle 1 + Angle 2 = [tex]180^{\circ}[/tex]

[tex]72^{\circ}[/tex] + Angle 2 = [tex]180^{\circ}[/tex]

Angle 2 = [tex]108^{\circ}[/tex]

Hence angle 4 is also [tex]108^{\circ}[/tex]
