3.3/3.4 day 1 warm easy practice Parallel Lines and Transversal

Given the figure, which of the following are valid?

• Angle 2 is congruent to angle 4 because they are a linear pair

• Angle 5 is supplementary to angle 2 because they are corresponding angles

• Angle 6 is supplementary to angle 3 because they are same side exterior angles

• Angle 4 is congruent to angle 6 because they are corresponding angles

• Angle 2 is congruent to angle 1 because they are alternate interior angles

If (x,2) is the solution of x+2y=15, how do you find the value of x?

• First plug in the (x,2) to the given equation.

• 2nd solve the equation x+2(2)=15

• 3rd get x=15-4
