Question

In triangle abc, if ab=bc and angle b = 70°,angleba will be :

Answer 1

Answer:

angle a = angle c=55°

Step-by-step explanation:

Given, AB = BC, ∠B=70

∠A=∠C=x ∘ (Isosceles triangle property)

Sum of angles,

∠A+∠B+∠C=180

∠A+70+<C=180

x+70°+x =180°

2x+70°=180°

2x=180-70°

2x=110°

x=55°

angle a = angle c=55°
