What is the measure of angle A please HELP I’ll give you BRAINLIEST

k0ka [10]

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) = $\frac{33}{42}$

A = $\text{cos}^{-1}\frac{11}{14}$

A = 38.21°

A ≈ 38°

Option (3) will be the correct option.

now take x=38, y =7

or x=31, y= 12
