Answer:

Explanation:

so do you recall the way to fit trig function onto triangles?

SOH CAH TOA helps you

m∠B = 68° , we can see by inspection, right?

since we have they Hypotenuse, or Hyp or H....

use CAH or Cos(Ф) = Adj / Hyp

Cos(22) = Adj / 14

14 * Cos(22) = Adj ( make sure your calculator is in degrees)

12.98 units , what ever they are this is AC ofc

now use SOH or Sin(Ф) = Opp / Hyp

Sin(22) = Opp / 14

14* Sin(22) = Opp

5.2445 this is BC ofc,

that's every angle and side of the triangle, :)
