Answer:
Option (3)
Step-by-step explanation:
By applying cosine rule in the triangle ABC,
BC² = AC² + AB² - 2(AC)(AB)cosA
5² = 3² + 7²- 2(3)(7)cosA
25 = 9 + 49 - 42cos(A)
25 = 58 - 42cos(A)
cos(A) =
A =
A = 38.21°
A ≈ 38°
Option (3) will be the correct option.
The answer is 28.26 because to find the area of a circle you need to do pie time radius squared.
