Question

5. The three angles of a triangle are in the ratio 2:3:4. Find their measures​

Answer 1

Step-by-step explanation:

let the angles be 2x, 3x and 4x.

from triangle property,

2x +3x+4x= 180°

9x=180°

x=20°

therefore,

2x=2×20=40°

3x=3×20=60°

4x=4×20=80°

Answer 2

Answer:

Let the angles of the traingle be x

then

2x,3x,4x

$\large{2x+4x+3x=180(Angle\:sum\:property}$

$\large{9x=180}$

$\large{x=20}$

now the angles are

$\huge{\mathcal{\blue{\boxed{2x=2(20)=40degree}}}}$

$\huge{\mathcal{\blue{\boxed{3x=3(20)=60degree}}}}$

$\huge{\mathcal{\blue{\boxed{4x=4(20)=80degree}}}}$
