Solve pqr

include all relevant calculations, . i'm trying to make sure i understand what i did wrong.

r = 15.9 m

∠P = 63.27°

∠Q = 26.73°

∠R = 90°

Step-by-step explanation:

"Solving a triangle" means to find all 3 side lengths, and find all 3 angle measues.

To find r, use Pythagorean theorem (since it's a right triangle)

  (7.15)² + (14.2)² = r²

          51.225 + 201.64 = r²

                 252.865 = r²

                       15.9 = r     (take the square root of both sides)

To find angle P, use Tan inverse.  (We have the side opposite and adjacent to the angle).  Tan x = opposit/adjacent so we have

  Tan^-1 P = 14.2/7.15

              P = 63.27

We have angle R = 90°, so angle Q is

Q = 180 - R - P

   Q = 180 - 90 - 63.27

           Q = 26.73°
