If the difference between two supplementary angles is 80⁰, then the smaller of the two angles is * 130⁰120⁰60⁰50⁰ |
| Answer» LET, the smaller ANGLE be XSO, the greater angle be 180 - xAccording to question (180 - x) - x = 80180 - x - x = 80180 - 2X = 80180 - 80 = 2x100 = 2xx = 100/2x = 50 degreeSo, the smaller angle is 50 degree. OPTION d) 50 degree is correct answer. | |
