Two straight lengths of wire are placed on the ground, forming vertical angles. if the measure
of one of the angles formed is 72º, what are the measures of the other three angles?

 72°, 108°, 108°

Step-by-step explanation:

Vertical angles are congruent (equal) so if one angle is 72° then its vertical angle is also 72°.

A vertical angle and its adjacent angle form a 180° angle, so the other two angles are each 180° - 72° = 108°

see image below

a = 11 : 4

b = 38

c = 1 for every 6
