Question

The angles of a triangle are in the ratio 3 4 5. calculate the smallest angle in the triangle

Answer 1

Ratio of all the angles of triangle = 3:4:5

We know that,

Sum of all the angles of a triangle is 180°

Let all the angles of triangles be 3x, 4x and 5x.

A/q,

➡ 3x + 4x + 5x = 180°

➡ 12x = 180°

➡ x = 180/12

➡ x = 15

so, all angles of triangle are :-

➡ 3x = 3(15) = 45°

➡ 4x = 4(15) = 60°

➡ 5x = 5(15) = 75°

Hope it will help u !
