#8: By definition, alternate exterior angles are angles on opposite sides of the outside of the lines that are congruent to each other. For this question, this could be represented by angles 1 and 8 and angles 5 and 4.

#6 If we know that ABC is a right triangle, then we know that one of the angles (the right angle) is 90 degrees. We also know that another angle is 40 degrees as shown in the picture. If all triangles add up to 180 degrees, then we know that the missing angle is 50 degrees. Based on the placement of angle ECD, we can add up the two sides of the triangle furthest away from angle ECD (90+40=130) so angle ECD equals 130 degrees.

Answer:

Angle 1 and Angle 5

Angle ECD = 130

Explanation:

Looking at the transversal, you can see that angles 1 and 5 are alternate exterior because they are on the outside and are on different lines.

Angle ECD = 130 because this angle is congruent to the sum of the farthest angles away from it, which are 40 and 90, so adding them together is 130, making that the answer.
