Answer 2

Answer:

A=80°

Step-by-step explanation:

angle ACB and angle ACD are linear angle

therefore,

<c +130=180

angle c= 50°

AB= AC ______________ given

angle B=angle C________ isosceles triangle theorem

angle B =50°

sum of all angles of traingle is 180°

A+ B + C=180

A+50+50=180

A +100=180

A =180-100

A=80°
