Answer:
FEA, DEF = 23 degrees
Explanation:
Angles FEA and DEF are alternate interior angles. Alternate interior angles are congruent.
Therefore, FEA is congruent to DEF, and:
x + 20 = 6x + 5
Now, we solve this equation to find the value of x:x + 20 = 6x + 5
x + 20 = 6x + 5
20 = 5x + 5
15 = 5x
3 = x
Now, we know that the value of x is 3. We can plug this value into the equations to find the values of the angles.
x + 20
3 + 20
DEF = 23 degrees
6x + 5
6(3) + 5
18 + 5
FEA = 23 degrees.
In fact, you only need to find the measure of one of the angles, because you know that they are congruent.
Hope this helps :) Please feel free to ask me any questions!
