Пошаговое объяснение:
Сумма углов равна ∠KOM+∠KON = 90°
3x-26°+x-12° = 90°;
4x=90°+12°+26°;
4x=128°;
x=128°/4;
x=32°.
∠KOM = 3x-26° = 3*32°-26° = 96°-26° = 70°.
∠KON = x-12° = 32°-12° = 20°.
-------------
Сумма углов равна ∠KOM+∠KON = 90°.
3x+20° + 2x+15° = 90°;
3x+2x=90°-20°-15°;
5x = 55°;
x=11°.
------
∠KOM=3x+20° = 3*11°+20° = 33°+20° = 53°.
∠KON = 2x+15° = 2*11°+15° = 22°+15° = 37°.
***********
x+4x-10° = 90°.
5x=90°+10°;
5x=100°;
x=100°/5;
∠KOM = x=20°.
∠KON=4x-10° = 4*20°-10° = 80°-10° = 70°.
