Question

in the given figure x y =2:3and /acd =120 fid thevalue of angle​

Answer 1

Answer:

Let the ratio be 2 a :3 a

Step-by-step explanation:

Using angle sum property of a triangle

                      2 a + 3 a + 120 = 180 degree

                               5 a + 120 = 180

                                        5 a  =180-120

                                            a =60/5

                                            a=12

Therefore,

angle 1 = 2 a

             =2*12

             =24

angle 2 = 3 a

             =3*12

             =36

Hope it helps

Answer 2

Answer:

let the ratio be 2x 3x

then, z=120+z=180°

= z = 180-120

= z = 60°

sum of two interior opposite angle = exterior angle

then 3x+2x=120

5x=120

x=120/5

x=24

Step-by-step explanation:

the value of angle a =2x= 2x24

48°

the value of angle b =3x =3x24

= 72°
