Your solution steps look correct, but the answer was not completed. Given that QR = 33.8 and PQ = 57.6, and Q is the right angle, then tan P = opposite / adjacent = QR / PQ = 33.8 / 57.6 = 0.586.
Then tan P = 0.586
Angle P = tan^-1 (0.586) = 30.4 degrees.

OFFERING 50 POINTS

Answer:

The volume will be 2600 L.

Explanation:

Initial temperature (T_{1}) = 25°C = (25 + 273) K = 298K

Final temperature (T_{2}) = 54°C = (54 + 273) K = 327 K

By using the combined gas law equation,

                                 \frac{P_{1} V_{1} }{T_{1} } = \frac{P_{2} V_{2} }{T_{2}  }

                       or, \frac{760* 1200}{298} = \frac{380* V_{2} }{327}

                      or, 3060 × 327 = 380 × V_{2}

                      or, V_{2} ≈ 2600 L

Hence the volume of the balloon will be about 2600 L.
