Assume that abd has a measure of 105. assign a variable and write an equation that will you determine the measure of dbc.

75

Step-by-step explanation:

So it is asking for the missing angle. Simply make an equation to find it.

X+105=180

X=180-105

X=75

Therefore 75 degrees is your answer.

parallel and congruent

step-by-step explanation:

the movement of translation is linear.   these have the same translation because you are using the same rule for each point of the triangle so you will see the same slope being used to get from a point on the triangle to its image.

same slope!   you should think parallel when you see those 2 word together (well unless it's the same line but it can't be because we are coming from different points here)

congruent! because each point is being moved the same distance.
