Question

The angle of a triangle ABC is 2x 3x 4x respectively find the angles of the triangle Show working

Answer 1

Answer:

40⁰,60⁰ and 80⁰

Step-by-step explanation:

2x+3x+4x=180⁰

9x=180⁰

x=180/9

x=20

Angles are :-

2x=2×20=40⁰

3x=3×20=60⁰

4x=4×20=80⁰

Check,

sum of all angle =40⁰+60⁰+80⁰ = 180⁰

Answer 2

Angles of the triangle are : 2x

3x

4x

We know according to angle sum property that all the angles of a triangle sum up to 180°

So..

2x + 3x + 4x = 180°

9x = 180°

x = 180 / 9

x = 20

2x = (2 × 20) = 40°

3x = (3 × 20) = 60°

4x = (4 × 20) = 80°
