I hope its clear that answer to the first part
Answer:
Transitive Property of Congruency;If parallel lines have a transversal, then alternate interior angles are congruent.
The Transitive Property of Congruency:
If 2 angles are congruent to a third angle, then they are congruent to each other. So, since angles 4 and 5 are both congruent to angle 1, they are congruent to each other.
Angles 4 and 5 are alternate interior angles. Therefore, if parallel lines have a transversal, alternate interior angles are congruent.
1 whole should be the answer
Answer:
the answer is explained below (tap on the photo to view it fully)
Divided both sides by 1/2
1/2x/(1/2)=14/(1/2)
x=14/(1/2)=14/0.5=28
The answer will be x=28
