Answer 1

Answer:

let angle B=x⁰

they said that AB=AC

So, Angle B=Angle C

In any Triangle sum of all angles is 180⁰

So,

angle B+angle C+angle A=180⁰

X+X+50⁰=180⁰

2X=130⁰

X=64⁰

Answer 2

Answer:

65°

Step-by-step explanation:

ab=ac

that means it is isoceles triangle and angle b= angle c

angle a+ angle b+ angle c=180°

50°+angle b +angle b=180°. .°. angle b =angle c

50°+ 2angle b =180°

2 angle b =180°-50°

2angle b=130°

angle b = 130°/2

angle b= 65°
