Answer:
Answer: x = [tex]\frac{25}{6}[/tex]
∠ABC = 53°
Step-by-step explanation:
Solution In given triangle, 2B=12x+3
12x+3
∠A = 86 , ∠C = 43°
We know that, Sum of all angles of triangle is 180°
86
∴ ∠A+ ∠B + ∠C = 180°
a
86 + 12x+3+ 43 = 180°
4-3
12x = 180° - 130
X = [tex]\frac{50}{12}[/tex] x = [tex]\frac{25}{6}[/tex]
с
∠ABC = 12x + 3 = [tex]\frac{12}{6}[/tex]x25 +3 → 50+3 = 53
