Equation of circle: 
My answer would be 65° because none of the other choices make sense!
This angle is clearly under 90°, which eliminates the choices of 92° and 138°. This angle is also clearly bigger than 27°, which eliminates this choice too!
I really hope this helped, if there’s anything just let me know! ☻
Answer:
Step-by-step explanation:
for missing angle of triangle ABC
let the missing angle be y
31+111+x=180(sum of interior angle of a triangle is 180 degree)
142+y=180
y=180-142
y=38 degree
x=y(being alternate angles)
x=38 degree
I think there's an error with this question. Mind to check it back and tell me the detail?
I think I'll be 6/13= 0.4615
