Question

anonymous · Answer

Two straight lengths of wire are placed on the ground, forming vertical angles. If the measure of one of the angles formed is 72°, what are the measures of the other three angles? Explain your answer.

anonymous · Answer

Well you have two angles at 72 deg, and then you have another two angles at (180-72)=108. The reason is because the sum of all four angles is 360. If two lines cross each other they will form four angles, two by two in equal size.
