Question

Va roggggg ,dau coroana !!!!!!

Answer 1

CM≡AB ⇒ CM≡BC (deoarece ABCD patrat) ⇒ΔCBM isoscel ⇒ m(∡CBM)≡m(∡BMC)

m(∡CBM)+m(∡BMC)=180°-135°

m(∡CBM)+m(∡BMC)=45°

m(∡CBM)=45°:2

m(∡CBM)=22,5° (sau 22°30')

m(∡BMC)=22,5°

m(∡ABM)=m(∡ABC)+m(∡CBM)=90°+22,5°=112,5° (sau 112°30')

Answer 2

Sper ca te-am ajutat.
