Zack, Rachel, and Maddie are unraveling a huge ball of yarn to see how long it is. As they move away from each other, they form
a triangle. The distance from Zack to Rachel is 3 meters. The distance from Rachel to Maddie is 2.5 meters. The distance from Maddie to Zack is 4 meters. Find the measures of the three angles in the triangle.
We are tasked to solve the three angles given that we have the measurements of the sides such as a = Zack to Rachel distance b = Rachel to Maddie distance c = Maddie to Zack distance
a =3 b =2.5 c =4
Solving the angles we need to use Law of Cosines: cos A = 2.5² + 4² -3² /2*2.5*4 A = 48.59°
