Question

three angles of a triangle are x°,2x°and 3x°.Prove that the triangle is right angled.​

Answer 1

Answer:

Step-by-step explanation:

x+2x+3x=180

6x=180

x=180÷6

x=30

1st angle is 30

2nd angle is 60

3rd angle is 90

So the triangle is right angled triangle

Answer 2

Answer:

x+2x+3x =180

6x =180

x =180/6

x =30

1st angle =30

2nd angle=30*2=60

3rd angle =30*3=90
