У нас треугольник прямоугольный, значит один из углов = 90°

Второй угол нам известен, найдем третий:

180°-90°-35°=55°

Ответ: Б

Отметьте пожалуйста лучшим решением и поставьте сердечко

Ответ:

Б.90° i 55°. Сума усiх кутiв трикутника = 180°. Якщо це прямокутний трикутник, один його кут перпендикулярний, тобто 90°. → 180°-90°-35°=55°. Тобто, 2 iншi кути дорiвнюють : 90° i 55°.
