plsss dauuu coroanaaa​

Answer 1

Răspuns:

Explicație pas cu pas:

a. d=A'C=35

Ab=270

AB=2,5k

BC=3k

Ab=AB×BC=270

2,5k×3k=270

k²=36 ⇒ k=6 ⇒ AB=15 si BC=18

b. In ΔABC aplicam pitagora

AC²=AB²+BC²

AC²=225+324

AC=√549=3√61

√61≅7,81

AC≅23,43

[AC]=23

c. V=Ab×h

In ΔAA'C aplicam pitagora

A'C²=AC²+AA'²

35²=549+AA'²

AA'=√676=26

V=270×26=7020
