Question

Write the missing alternate interior and alternate extirior angles.With explanation ​

Answer 1

In figure 1:

• The value of the exterior angle alternate to 112° is 112° because we know if two lines are parallel and are intersected by a transversal, then the alternate exterior angles are considered as congruent angles or are equal in measurement.

• The value of the exterior angle alternate to 68° is 68° because we know if two lines are parallel and are intersected by a transversal, then the alternate exterior angles are considered as congruent angles or are equal in measurement.

In figure 2:

• The value of interior angle alternate to 130° is 130° because we know that two parallel lines are crossed by a transversal are considered as congruent angles or are equal in measurement.

• The value of interior angle alternate to 50° is 50° because we know that two parallel lines are crossed by a transversal are considered as congruent angles or are equal in measurement.

Answer 2

Step-by-step explanation:

proteins

15.3. 8 Animal fibers. Animal fibers are the second most widely used natural fibers after vegetable or plant fibers. They are generally comprised of proteins, and can be potential reinforcements in composites.
