Answer:

let 2 equal angles be x

therefore, 3rd angle: 2x-16

as we know,

sum of all angles of a triangle is 180°

x+x+2x-16=180°

4x-16=180

4x=196

x=196/4

x=49°

hence, all angles are x=49°

x=49°

2x-16=2(49)-16=98-16=82°

all angles= 49°, 49°, 82°

Step-by-step explanation:

In triangle ABC

let angle b=x

angle b= angle c = x

angle. a= 2x-16

angle a+b+c=180(sun of all angles of a triangle is 180)

x+x+2x-16=180

4x-16=180

4x=180+16

x=196\4

x=49
