ABC has ∠BCA = 2∠BAC. Side BC is extended through C to a point D so

that AC = CD. If AB = 3 and BC = 2, find AD.

```````````````````````````````````````````````````````````````````````

AD = 3.75

Sides: a = 2 b = 2.5 c = 3

Area: T = 2.48

Perimeter: p = 7.5

Semiperimeter: s = 3.75

Angle ∠ A = α = 41.41° = 41°24'35″ = 0.723 rad

Angle ∠ B = β = 55.771° = 55°46'16″ = 0.973 rad

Angle ∠ C = γ = 82.819° = 82°49'9″ = 1.445 rad
