Question

4. The angles of the triangle are in the ration 2:3:4. Find them.​

Answer 1

Answer:

then angle of triangle are =2x=40⁰

=3x=60⁰

=4x=80⁰

The angles of triangle are 40, 60 and 80

Step-by-step explanation:

It is given that the angle of triangle are in the ratio 2 : 3 : 4. Let the angles are 2x, 3x and 4x.

According to the angle sum property, the sum of interior angles of a triangle is 180 degree.

2x+3x+4x=1802x+3x+4x=180

9x=1809x=180

x=20x=20

The value of x is 20.

2x=2(20)=402x=2(20)=40

3x=3(20)=603x=3(20)=60

4x=4(20)=804x=4(20)=80

Therefore the angles of triangle are 40, 60 and 80.

Answer 2

Answer:

40°, 60° and 80°

Step-by-step explanation:

Let the given angles of the triangle be 2x, 3x and 4x.

We know that,

Sum of all angles of a triangle = 180°

2x+3x+4x = 180°

9x = 180°

x = 180°/9

x = 20°

The angles are,

2x = 2(20°) = 40°

3x = 3(20°) = 60°

4x = 4(20°) = 80°

Therefore, the values of the angles of the triangle are 40°, 60° and 80°.

Hope it helps you.

Good Luck.
