Given: Lines y and z are parallel, and ABC forms a triangle.
Prove: m25+ m22 + m26 = 180° which could be the missing reason in step 3

This problem has missing information, so I've provided my own diagram below.

By Alternate Interior Angles:

Angles ∠6 and 48 degrees are supplementary:

Internal angles of every triangle add up to 180 degrees:

Finally:

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
