Answer (1)
Answer:You're on the right track! Here's how to solve the problem step-by-step: 1. Combine the known angles: - 63° + 135° + 90° = 288° 2. Set up the equation: - 288° + x + x = 540° 3. Simplify the equation: - 288° + 2x = 540° 4. Isolate the 'x' term: - 2x = 540° - 288°- 2x = 252° 5. Solve for 'x': - x = 252° / 2- x = 126° Therefore, x = 126°Step-by-step explanation:tama nmn din Po ung sagot nyu
