QuestionGiven the triangle
14 , find the measure of angle $A$ using the Law of Cosines. Picture is not drawn to scale $$A=$$ $\square$ degrees

Studdy Solution
Calculate the measure of angle $A$ using the inverse cosine function:
$$A = \cos^{-1}\left(-\frac{77}{105}\right)$$
Use a calculator to find the angle:
$$A \approx 143.13^\circ$$
The measure of angle $A$ is approximately:
$$\boxed{143.13^\circ}$$
