Question

please answer the following question

Answer 1

Answer:

x = 20

Step-by-step explanation:

Angle BOA = 3x+10  { Equal sides have equal angle opposite to r }

Angel COD is = 3x =10

IN TRIANGLE COD :-

Angle ODC is 3x+10

According to questio;-

3x+10+3x+10+2x = 180  [ sum of angles of triangle ]

8x = 180 -20

8x  = 160

x = 20

Answer 2

Step-by-step explanation:

Angle BOA =3x+10 (equal sides have equal opposite angle to r)

Angle COD is=3x+10

In triangle COD:-

Angle ODC is 3x + 10

According to question

3 X + 10+ 3 X + 10 + 2 x=180 (sum of all angles of a triangle)

8x=180-20

8x=160

x=20
