Answer:
LB=65°
LC=65°
Step-by-step explanation:
Given:-
∆ABC, LA =50, IF AB= AC
To find:-
Find LB, LC
Using formula:-
The sum of three angles in a triangle is 180°
Solution:
In ∆ABC, AB=AC
=>LB=LC
The angels opposite to equal sides are equal
Let LB=LC=X°
and LA=50°
=>LA+LB+LC=180°
=>50°+X°+X°=180°
=>50°+2X°=180°
=>2X=180°-50°
=>2X=130°
=>X=130°/2
=>X=65°
