Question

» The angles of a triangle are in the ratio 3:45. Find the angles. (3M)​

Answer 1

Answer:

lets take the triangle ABC

and the ratio as 3:4:5 = 3x , 4x,5x

and we know that the angle sum property of triangle is equal to 180deegre

hence , angle A+B+C=180 deegre

3x+4x+5x=180

12x=180

x=180/12

x=15deegre

and by the putting the value of x we get,

3x=3x15=45

4x=4x15=60

5x=5x15=75
