Answer:
38 degrees
Step-by-step explanation:
By the Law of Cosines,
5² = 3² + 7² - 2(3)(7) cos A
5² - 3² - 7² = -2(3)(7) cos A
-33 = -42 cos A
cos A = 33/42
A = arccos(33/42), which is about 38 degrees.

Answer:
B.
Step-by-step explanation:
In statement (1), we are given that m∠BAC=m∠BCA
If the two angles are congruent, this means that the sides opposite the angles are also congruent. These sides are AB and BC. Therefore:
AB=BC | B. sides opposite equal angles are equal
:Done
*The side opposite a given angle is the side towards which the angle opens up to. For example, ∠BAC opens up towards the side BC, and ∠BCA opens up towards side BA.
