Question

the angles of a triangle are in the ratio 2:3:4 then the angles are​

Answer 1

Answer:

Step-by-step explanation:

Let the angles be 2x, 3x and 4x respectively.

Then,

$\because 2x+3x+4x= 180^\circ$

$\implies 9x = 180^\circ$

$\implies x= \frac{180^\circ}{9}$

$\therefore x= 20^\circ$

Then the angles are:

$2x = 2 \times 20^\circ = 40^\circ$

$3x = 3 \times 20^\circ = 60^\circ$

$4x = 4 \times 20^\circ = 80^\circ$
