∠NOR = ∠ROP = 52,5°, ∠POS = 75°, ∠ROS = 127,5°
Объяснение:
1) ∠NOR = ∠ROP = 1/2∠NOP = 105/2 = 52,5°
2) ∠POS = 180 - ∠NOP = 180 - 105 = 75°
3) ∠ROS = ∠ROP + ∠POS = 52,5 + 75 = 127,5°
∠NOR = ∠ROP = 52,5°, ∠POS = 75°, ∠ROS = 127,5°
Объяснение:
1) ∠NOR = ∠ROP = 1/2∠NOP = 105/2 = 52,5°
2) ∠POS = 180 - ∠NOP = 180 - 105 = 75°
3) ∠ROS = ∠ROP + ∠POS = 52,5 + 75 = 127,5°
