I was going to give you all the answers, but quite frankly I have my own work to do.
Is there a specific one you're having trouble with, or just all of them in general? |

that would be an equilateral triangle, or whatever u call one with 2 sides the same size, so the bottom 2 angles are both 71
71+71 = 142 (i think)
189-142=47 degrees
hope that helps |

| And the measurements are simply there to help you infer that the two angles that aren't x are equal. |

wait, is that right? idk
anyway, the centimeters are just there to show that both sides are the same size |

"189-142=47 degrees"
Wait, why are you subtracting from 189? |

"how"
Huh, that's a good question.
If those two sides are equal (4cm and 4cm), then the angles are equal too (exceptions may apply), so then you add the angles, getting 142, and subtract from 180. |

| I'm honestly going to feel really bad if I somehow messed that up, though I doubt I did. |

I'm godawful in math, but geometry is one thing that actually comes naturally for me.

In the top, from left to right: 1) x = 130 2) x = 51 3) x = 128

I could give you some hints if the filter didn't decide to block my post because it dislikes math.
