∠ABC = 180 - 75 = 105° (смежные)

∠ACB = 180 - 105 - 35 = 40° (сумма углов треугольника равна 180°)

Ответ: ∠ABC = 105°, ∠ACB = 40°

Предположим, что ⛛ABC + D =>

А = 35

BCD = 75

A + B + C = 180

B = BDC - A = 75 - 35 = 40

C = 180 - A - B = 180 - 35 - 40 = 105

After that he will prescribe some treatment, pills, tablets or some other medicine which we can buy at the chemist's. He will recommend you to stay in bed for some time.
