Help me find the missing angle

Answer

x=26

Step-by-step explanation:

77+77+x=180

154+x=180

180-154=x

the missing angle is 26

Step-by-step explanation:

77+77=154

180-154= 26

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.

only 10/60 isn't equivalent

hope this : )
