Question

ज्ञात कीजिए।
The three angles of a triangle are in the ratio 3:4:5 then find the value of all angles

​

Answer 1

Answer:

45°, 60° and 75°

Step-by-step explanation:

Let the ratio 3:4:5 be 3x 4x and 5x.

According to question:-

3x + 4x + 5x = 180°(angle sum property)

12x = 180°

x = 180°/12

x = 15°

3x = 3*15° = 45°

4x = 4*15° = 60°

5x = 5*15° = 75°

Answer 2

Answer:

let three angles of a triangle are 3x,4x and 5x

sum of all angle of a triangle is 180°

A.T.Q

3x°+4x°+5x°=180°

12x°=180°

x°=180°/12

x°=15°
