The sample taken is from the employees that will work on the highway, but we need to know the resident's opinion. The workers will have a different opinion than the average person, so this is not an accurate conclusion.

Find m\angle Am∠Am, angle, A.<br> Round to the nearest degree.

Oxana [17]

Answer:

m∠A = 106°

Step-by-step explanation:

All three sides of the triangle are given in the question.

To find the measure of included angle A between two sides we will apply cosine formula,

BC²= AB² + AC² - 2(AB)(AC)cosA

(13)² = (10)² + (6)² - 2(10)(6)cosA

169 = 100 + 36 - 120cosA

cosA = $\frac{-169+136}{120}$

cosA = -0.275

A = $\text{cos}^{-1}(-0.275)$

A = 105.96°

A ≈ 106°

Therefore, m∠A = 106° will be the answer.
