For triangle XYZ, m∠X = (7g + 12)° and the exterior angle to ∠X measures (2g + 60)°. Find the measure of ∠X and its exterior angle.

Interior angle = 49°; exterior angle = 131°

Interior angle = 131°; exterior angle = 49°

Interior angle = 96°; exterior angle = 84°

Interior angle = 84°; exterior angle = 96°
