Question

In triunghiul dreptunghic abc ,m (A)=90 de grade ,ad perpendicular bc ,d apartine (bc)se dau: a)cd =16,2 cm si ac=27 cm .calculati bc,bd si ab..b) bd=27 cm si cd=48 cm .calculati bc ,ab si ac....ma ajutati va rog!!!

Answer 1

a)
teorema catetei
AC=√DC×BC
27=√16,2×BC
BC=27²/16,2=45 cm
BD=45-16,2=28,8 cm
AB=√28,8×45=√1296=36

b)
teorema catetei
BC=27+48=75
AB=√27×75=√2025=45
AC=√48×75=√3600=60
