Question

Q.2)Find the angles of a triangle which are in the ratio 1:2:3​

Answer 1

Answer:

The Angles are 30 , 60 and 90

Step-by-step explanation:

The sum of the angles inside the triangle ( interior angles ) add upto 180 . This property of a triangle is called as " Angle Sum Property ".

Let the Common factor of the ratios be x

1x + 2x + 3x = 180

3x + 3x = 180

6x = 180

x = 180 ÷ 6

x = 30

angles are 1x , 2x and 3x ,

1x = 1 × 30 = 30

2x = 2 × 30 = 60

3x = 3 × 30 = 90

Verification :

30 + 60 + 90 = 180

90+ 90 = 180

180 = 180

Hence Verified

Answer 2

1st step =The addition of all angel in Triangles =180

1x+2x+3x = 180

6x = 180

x = 180/6

x = 30

then

1x = 30

2x = 30*2 = 60

3x = 30*3 = 90
