Answer 1

Answer:

blal

Step-by-step explanation:

Answer 2

1)A+B+C=180°

x+30+3x-30+4x-60=180

8x=240

x=30

A=60°,B=60°,C=60°

hence equilateral

2) x+42+4x-12+3x+6=180°

8x=216

x=27

A=60°,B=60°,C=60°

hence equilateral

1)A+B+C=180

110+C=180

C=70°

two angles are equal......hence isosceles

2)150+C=180

C=30°

two angles are equal ...hence isosceles
