GIVEN, the RATIO of angles of a triangle is 2 : 4 : 3. LET the angles of a triangle be ∠A, ∠B and ∠C. HENCE, the smallest angle of a triangle is 40°.

Explanation:

We know that the sum of the angles of the triangle=180

We know that the sum of the angles of the triangle=180 ∘

We know that the sum of the angles of the triangle=180 ∘

We know that the sum of the angles of the triangle=180 ∘ Let the angles be 2x,4x and 3x.

We know that the sum of the angles of the triangle=180 ∘ Let the angles be 2x,4x and 3x.So, 2x+4x+3x=180

We know that the sum of the angles of the triangle=180 ∘ Let the angles be 2x,4x and 3x.So, 2x+4x+3x=180 o

We know that the sum of the angles of the triangle=180 ∘ Let the angles be 2x,4x and 3x.So, 2x+4x+3x=180 o

We know that the sum of the angles of the triangle=180 ∘ Let the angles be 2x,4x and 3x.So, 2x+4x+3x=180 o 9x=180

We know that the sum of the angles of the triangle=180 ∘ Let the angles be 2x,4x and 3x.So, 2x+4x+3x=180 o 9x=180Hence, x=20

We know that the sum of the angles of the triangle=180 ∘ Let the angles be 2x,4x and 3x.So, 2x+4x+3x=180 o 9x=180Hence, x=20The smallest angles is 2x i.e. 40

We know that the sum of the angles of the triangle=180 ∘ Let the angles be 2x,4x and 3x.So, 2x+4x+3x=180 o 9x=180Hence, x=20The smallest angles is 2x i.e. 40 Hope it is helpful
