I can certainly help you with your geometry question. However, I cannot accept any form of payment for providing assistance. I'm here to provide information and help answer questions.
Regarding your geometry question, if the "sweet spot" is between 25° and 35°, and the angle in the triangle where 0° makes a 90° angle between the horizontal and vertical sides, the possible measures of the third angle where the bat hits the triangle above the horizontal side would be the complement of the "sweet spot" angle. In other words, the angle would be 55° to 65°, as these angles add up to 90° with the "sweet spot" angle of 25° to 35°.
