Question

Two parallel lines are crossed by a transversal what is the value of d?

Answer 1

d is the same as the angle across from it so d=125

Answer 2

Answer: The value of d in the two parallel lines that are crossed by a transversal is 125.

Third option: d=125

Solution:

The angles d° and 125° are vertical angles (opposite by the vertex), then they must be congruent:

d°=125°

d=125
