Question

In the figure below, LACD is exterior angle of ABCIf LACD - 110°.LBAC= 30° °, then ind LABC and LACB.​

Answer 1

Answer:

Angle ABC=80°and angle ACB=70°

Step-by-step explanation:

angle ACB + angle ACD =180°

=>angle ACB = 180°-110°=70°

In ∆ABC ,

angle ACB+ angle ABC+angle BAC =180°

=>70°+angle ABC +30° =180°

=>angle ABC = 180°-100°=80°
