If 1 measures 135°, what is the measure of 6? (Lines b and c are parallel.)

135°

65°

90°

45°

The Question is Incomplete, the Complete Question is with figure is below.

Therefore,

The Measure of angle 6 is

Step-by-step explanation:

Given:

m∠1 = 135°

Lines b and c are parallel.

To Find:

m∠6 = ?

Solution:

Linear Pair:

A linear pair of angles is formed when two lines intersect.  

Two angles are said to be linear if they are adjacent angles formed by two intersecting lines.  

The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.  

Example

∠ 1 and ∠ 2 ∠ 1 and ∠ 3 ,etc

Substituting the values we get

Now,

Lines b and c are parallel.  .Given

When Two lines are Parallel Alternate interior angles are equal

∠ 3 and ∠ 6 are Alternate Interior angles

But

    ...Transitive Property

Therefore,

The Measure of angle 6 is

answer:
