Question

S
2) The angles of a triangle are in the ratio 3:4:5 find the angles.​

Answer 1

Answer:

Here is your answer

Step-by-step explanation:

3x+4x+5x=180

12x=180

x=180/12

x=15

3x=3×15=45 degree

4x=4×15=60 degree

5x=5×15=75 degree

so all angles are 45,60,75 degree

Answer 2

Step-by-step explanation:

let the angle is x

then,

angles are =3x, 4x , 5x

total sum of triangle=180

then,

3x+4x+5x=180

12x=180

x=180÷12=15

then,

4x=4×15=60

3x=3×15=45

5x=5×15=75

then, the angles are =60 , 45 and 75 degrees
