Question

Ajutatima plsss dau coroana

Answer 1

Răspuns:

1. 1=55 grade si este congruent cu 3=tot 55 grade

55+55=110 grade cele 2 unghiuri

360-110=250grade ramase pt unghiurile 2 si 4

dar si ele sunt congruente

250:2=125 grade fiecare unghi

2. 5=62grade

fiind congruent cu 7 are tot 62 grade

62+62=124grade

360-124=236grade ramase pt unghiurile 6 si 8

236:2=118 grade fiecare pt ca sunt congruente

Answer 2

$\it 2)\\ \\ \hat1=\hat5=62^o\ (unghiuri\ corespondente)\\ \\ \hat3=\hat1=62^o (unghiuri\ opuse\ la\ v\hat{a}rf )\\ \\ \hat7=\hat5=62^o\ (unghiuri\ opuse\ la\ v\hat{a}rf )\\ \\ \hat2=118^o\ (suplementul\ lui\ 62^o)\\ \\ \hat4=\hat2=118^o\ (unghiuri\ opuse\ la\ v\hat{a}rf )\\ \\ \hat6=\hat4=118^o\ (alterne\ interne) \\ \\ \hat8=\hat4=118^o\ (unghiuri\ corespondente)$
