Ответ:

Step-by-step explanation: 115 minus 8 is 107
Ответ:
132
Step-by-step explanation:
using sinus
m<ADB = ∅
sin 120/35 = sin ∅/30
((√3)/2)/35 = sin ∅/30
(√3)/70 = sin ∅/30
sin ∅ = (30√3)/70
sin ∅ = (3/7)(√3)
∅ = sin-¹ (3/7)(√3) (using calculator)
∅ = 47.928°
∅ ≈ 48°
then ADC = 180 - ADB = 180 - 48 = 132°
