Willow Mckay · Answer 1

Using the law of cosines we can solve for the length of the third side:

a^2 = b^2 + c^2 - 2*b*c*cos (A)

a^2 = 11^2 + 14^2 - 2*11*14*cos (65)

a^2 = 186.8336

a = √186.834

a = 13.67

The third side is 13.67 inches long. (Round the answer as needed)

Carlos Valencia · Answer 2

less than 25 inches

The sum of any two sides of a triangle must be greater than than the third side.

Since 11 + 14 = 25, the third segment must be less than 25 inches

The correct answer is less than 25 inches.
