Question

the angles of a triangle are 2xdegree 3x degree and 4x degree. find the measures of each angle ​

Answer 1

Step-by-step explanation:

let the angles of a triangle be 2x,3x and 4x.

since, sum of the angles of a triangle is 180°

ATQ,

2x + 3x + 4x = 180°

9x = 180°

x = 180°/9 = 20°

therefore, first angle = 2x = 2 × 20° = 40°

second angle = 3x = 3 × 20° = 60°

third angle = 4x = 4 × 20° = 80°

hope it helps you

Answer 2

Answer:

let's first angle is 2x°

second one is 3x°

and third one is 4x°

as we know that the sum of three angles on triangle is equal 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°
