Answer:

the third angle must be 55

Step-by-step explanation:

a triangle must have an 180 degree angle in total

180-125=55
  • Sum of two angles=125°

We know in a triangle sum of angles=180°

Let the other angle be x

ATQ

[tex]\\ \sf\longmapsto x+125=180[/tex]

[tex]\\ \sf\longmapsto x=180-125[/tex]

[tex]\\ \sf\longmapsto x=55°[/tex]
