Plz solve this problem.​

Answer 1

Answer:

x=14

Step-by-step explanation:

OAB=36 (Isosceles triangles have base angles equal)

OAC=40 (Isosceles triangles have base angles equal)

So, BAC=36+40=76

OBC=OCB=x (Isosceles triangles have base angles equal)

ABC=36+x

ACB=40+x

Sum of angles of a triangle is equal to 180 degrees

Therefore,

ABC+ACB+BAC=180

36+x+40+x+76=180

Solve...

x=14
