What is the measure of angledcf? three lines extend from point c. the space between line c d and c e is 75 degrees. the space between lines c e and c f is 54 degrees.

  129°

Step-by-step explanation:

If CE is between CD and CF, then angle DCF is the sum of the given angles:

  75° +54° = 129°

number one is the correct answer

step-by-step explanation: dogs and cats are mentioned, no other animals

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
